Exactly what i was going too say. Glas isent really flat but im guessing its flat enough but a mirror is probably flatter! best thing would be a the precision flat stones but there pretty pricy. Good if your planning on mesuring stuff tho
I would suggest anyone flat lapping for the first time to use the same flat surface (start to finish) and super cleaning between swaping grit numbers. It will take longer but it will come out near perfect
I would suggest watching a youtube channel like oxtoolco or robrenz these people are lapping for a perfect size down to .0001 of an inch and smaller. You do not need that for your cpu, but the techniques use to keep your cpu level is a good thing to learn will make your cpu lapping come out better.
take it to a machine shop and have them mill it down. Cover everything you don't want milled with wax to keep anything from getting under the die or what ever it is. If you were really brave, you could have your CPU cut with a vee pattern and the cooler with a mirror image vee pattern so they would both have way more surface area. A shop with a good mill could cut them to less than 0.001 mm.
I would suggest don't do it at al, nothing a single cpu user encounters would or will ever require all this butchery, this is just for fun with no practical application outside of not understanding why people who need this power use multiple servers to achieve it.
I think if you had measured the cpu before and after grinding and lapping with a micrometer or vernier caliper, you could turn down the standoff height the same amount to compensate using a lathe and you could have used any cooler on the chip with the proper pressure (You would have to keep the shorter standoffs with the chip after modifying it)
@T. N. i used a calliper, but there was actually no need got it perfect, but it did come in handy to know how much i took away, and i did not manage to get the whole 1.4, i might lap it down more, but my hands are bleeding already as i did it manually took a few hours to grind down a bit more than 1mm
Im a knife maker and when we mirror polish a knife which can be to around 2000 grit sandpaper a trick we use is each grit go in 1 direction. the next grit go in another, That way if your going left to right and see scratches up and down you know those are scratches from the previous grit and need to be worked out. Might have to use a magnifying glass to see the real fine grits,.
Well a mm is pretty big actually. Even cheap FDM 3D printers (setup correctly) typically have a repeatable tolerance below 0.3mm. Above that starts becoming a problem more than you might think. Sub 0.1mm (100um) is where it gets tricky and typically where a lot of professional machining is.

You can also use a sanding/polishing product called Micro Mesh to reduce the micro scratches on the heat spreader. Originally developed to sand/polish aircraft windshields and canopies to remove micro scratches and restore visibility (yes it's that fine). The sheets go to insane grits like 20,000.
@@3DxPOD been running like this for almost 3 years without issues yet 🤷🏻♂️ at this point if it causes something detrimental to my rig I’ll just build a new one
Change between all the sides when lapping to minimize unintentional gradients in the surface. Also, if you polish the CPU and the heat transfer block until they physically bond, you will get the best heat transfer. It is pretty cool to see two pieced non-magnetic of metal act like they are magnetic. Looks Great!
Prior machinist and folding knife Maker here, you should never lap with the power sander. When you're lapping a cpu or anything else you want it to be flat and parallel. Using a sander, no matter how flat your platen is, putting too much pressure on one side will cause it to no longer be parallel. Using a surface plate and a figure 8 pattern while turning often is going slowly is your best bet of staying flat and parallel. Yes it takes much longer but precision always does And I wouldn't trust using a surface grinder on a cpu or IHS
It's cool that delidding is back in style with these cpus. I delidded my old 8700k, and that turned out to be tons of fun, having the fastest cpu on the block. I sorta won the silicone lottery wirh that, managed a 5.3 all core.
Looking at that huge ass heatspreader i'm definitly gonna delid it when i get mine next week. I think it's the best cpu to do that with. Derbauer got 20C. Lapping just seems to be more work than delidding for less temperature gain.
@@alext9558 No, actually i'm still waiting for my custom waterloop. I just have an AiO now so i don't delid yet. But temps are good enough. Though i had to limit cpu to 80C + slight undervolt and it only reaches ~5.1 then which is still blazing fast. Stock 7950x reaches 95C+ very quick. I feel sorry for the users who get this and have no idea about bios and customizing. I'll try to overclock it to 5.7 when i get my loop.
personally gonna just lap it since that feels safer to me and I dont need any extra tools or parts for it. I can just 3d print the holder for it for lapping
If you’re going to go for gold and void warranty it feels like a delid and mount swap would be the best way to go. Lapping seems a lot of work for a halfway result.
problem I can see with that was how hard it was to get the mounts set up. Not sure if he was at the limit of what he could do or not. Personally, to save the 5-6 C I think it would be great as long as I could get a cooler on it. I know 5-6C isn't much but that was from pushing danger zone into more comfortable territory.
Well, lapping is marginally safer as long as you don't try to lap the max amount of 1.2mm. say, go down by 0.8 to 1.0mm. With delidding, one can easily damage the substrate and/or dislodge one of the caps.
Lapping is still a significantly lower risk of outright killing the CPU compared to delidding. Honestly for what it can do I'd consider it a worthwhile mod for somebody interesting in a heavy OC, but doesn't have the money to spend on a second CPU if one dies.
Jay, if you use a figure "8" motion it will make it easier to get a flat finish. Circular motion leaves point in the middle. Back and forth leaves a ridge across it. Think of it this way, the direction you move it digs in on the forward moving face/side. Push it north and the north end digs in. Same theory why Brembo brakes often use smaller disk puck on one end of the pad. Terry from Australia.
You know they make concave mirrors for telescopes using the same technique as Jay is using for a flat surface except they using a particular grinding motion. If you do it wrong you can end up with a convex or concave surface.
Even with the lapping, it's crazy how much heat is pouring out of that CPU. I remember it wasn't that long ago we only needed a 120mm radiator to deal with a CPU, and now it seems that 360mm of radiator won't be enough when talking about the long gaming/ intensive software sessions. Great video!!
appearently you don't... according to hardware canucks' testing the 7950X does perfectly fine even under a 120mm tower cooler. The whole cooling issue seems a bit overblown by Jay.
@@cosmic_cupcake i mean "perfectly fine" is subjective with this series of CPU's because they are designed to keep in the range of 95 C. So yes you can cool the chip with anything, but the performance you get will change drastically if it has better cooling. It will always try to hit 95 C and throttle if you exceed that limit. "Perfectly fine" does not mean what it used to mean for previous generations. I think I remember just fine.
We'll soon learn how much more de-lidding gets us. I bet i's not really worth the risk. At least with lapping you approach the danger level slowly and can stop.
That's interesting because I'm more willing to delid, It is much easier. Getting a perfectly flat surface lapping is way harder than people think. I've delidded and it's very easy running a thin knife through the glue.
Next time you replace the belt grinder you should get one that has the vertical disc plate grinder and rest plate. Makes that job a whole lot easier. 👍
I just gained the courage and lapped the IHS on my 7950x3d. Didn't go down to far since I don't have the Thermal Grizzly product to help. So a half degree difference but noticed my computer was much quieter during gaming. Before it used to scream to keep it normal temperature ranges. Keep doing this type of content!
The hook and eye mounting system would probably be OK without modification. It's spring loaded and only the CPU holding the cooler up. I'm not convinced the thickness reduction is what worked, rather the better contact surface.
@@vgernyc it's just the code name for the denser node with more cores. It's not specifically epic it'll also be used in threadripper. There's also a chance they could use it as a last ditch effort if intel catches up because it's double the density so if they somehow wanted to shoehorn more cores on am5 before they drop Zen 5 that would be the way they could do it. They also kind of hinted at the fact that it would be double the cores for the same power which is why I think they may actually refine this. I didn't mean to imply that they're going to somehow drop some weird core revision of current zen 4 that's going to quote, tame the power. They are not doing that. Zen 4 3D and Zen 4C are indeed supposed to be further refinements on the same node so there is a chance they will not run quite so aggressively hot, and I feel like if they have a chance to reign that in a little bit why wouldn't they. They clearly pushed Zen 4 as hard as they possibly could to make sure they stayed ahead of raptor lake, or at least extremely competitive with it.
I think Im going to do this as well, but i started wondering if there is a way to seal around the edge of the IHS to prevent anything from getting underneath during the lapping process. The thought of copper contamination under there doesnt sit well with me, and theres realy no way of knowing 100% if you've cleaned it all out afterwards. Im not sure what materials would be safe for this job, but the 1st thing that came to mind was some sort of clay as i would assume it should be safe when in contact with the SMDs around the edge of the ihs. I also considered a small bead of hot glue as that stuff always pulls away cleanly once dry, and would be more robust than clay, though im not sure if it would be too hot for those SMDs, or if it would let go of them and not pull them off at removal time (probably not, but nothings impossible). I dont think tape would seal well enough, so thats out, and thats about where i ran out of ideas. Anyone else have any thoughts along these lines?
hey jay i realy love these experiments to see the temp diferences. but i would like to see if there is an difference with lapping with sanding paper vs good enough whetstones. you can even polish it with an extremely high grid to smooth out the height difference as with sharpening knives. and to get an perfectly flat stone you have flatening/maininance stones to make the whetstone flat(if that is anny concern at all)
I love my 7900x ! i just got it up and running last night with 64gb of ram, 4 DIMMS working at their rated 6000mhz ! I applied some tweaks to the Precision boost overdrive in my Asus board and managed to unlock sorcery that made my CPU run cooler with less power draw and still maintained my performance. I ran one pass on Cinebench R23 multi core and got 27995, and my CPU did not exceed 52c for the entire run, i have a Noctua D15s with its stock fan. This thing runs cooler now than my 5800x did.
You could have easily exceeded 95 C using the belt sander. Wet sanding is your friend when trying to remove metal or plastic! (I have the same sander and can easily melt PLA from my 3 D printer if I get too aggressive.)
I'm glad Jay's a car guy being a diesel mechanic my self I was thinking of polishing I understand the insulting aspect as well so that's a no no but would be interesting if u could cnc mill up to 1 micron error then it would be perfectly flat with no valleys or peaks from scratches
Jay figuring out you can reuse original hardware is the gem of info in this video. So flippin cool Edit: Hey since you were able to get the z axes height lower with the original hardware, couldn't you take more off the ihs now?
2 years in having a 7950x and ive opted to just lapp my cpu vs upgrading. At stock I was getting your r23 score of around 38k after you lapped. With tuning I can easily go over 40k, so with more thermal headroom I can make my chip an absolute monster.
Jay you shoulda gone all the way and showed us the 1.2 mm result. I was hella curious what you’d get, and without reality to settle me down, I keep wondering “what if it would have dropped 10-15 degrees if he went that last .4”….
It’s not going to drop another 10-15 like that, probably 5 C is realistic and 10 is very generous. Direct die only takes about 20 C off so this would have to be less than that
Yeah do not expect miracles from another 0.4mm, but at least he did the test and seeing results for me at least totally worth it, as lapping still has protection for the die, and you shave off like 10-15degrees which is a big improvement from 95, realistically speaking no cpu will run full tilt, but reducing temps increases significantly cpu life and gives extra performance
Igor's Lab did some testing of the 7950x vs th 5950x. The 7950x produces about 20w more heat and runs about 9C hotter. I would bet that going down to the same IHS thickness as the 5950x would get you about 8-9C lower than the stock 7950x IHS.
Linus Tech Tips said in their "We killed it... but then SUCCESS!!!" vid that you DO want scratches, but that was when they delided the CPU and were lapping the actual DIE itself so they could liquid metal it which is obviously way better than regular goo and probably means that large scratches don't make nearly the difference that they would if you were using regular thermal goo. Am I wrong? Is there more too this? I lapped the IHS on my 3900x and I used sharpening stones for knives and even went down to some special hyperfine grit paper of 300,000 grain, I made that IHS the smoothest thing I had ever touched, like actually haha. No polish used. Didn't really notice a huge difference in the thermals lol. A degree C was about all I got.
Yeah now if they could only find a way to educate the masses into understanding measuring a few MHz in cpu speeds is a fools errand and far less important than other factors.
I'd expect tempered glass that thin to bow really easily. A 9x12x2 granite surface plate is like $60 on Amazon. Certified flatness to 0.0001" (0.0025mm) If you lap cpu and cooler both with that plate you should be able to get them to the point where they'll stiction together.
I have to admit, I am still surprised that AMD decided to go for a thick-as-heck IHS as its solution to AM5 processors being shorter than AM4. It seems like it would be much more reasonable to do any of the other 3 options I can think of: --Raise the whole mount on the socket side, such that the chip just sits higher --Put out specs for what the new height target is and work with as many of the big names in coolers as possible to help them have brackets ready to adapt their current hardware to AM5 on launch day --The above but also set up deals with those cooler manufacturers such that anyone buying a 7000 series processor gets a code they can use to get a free adapter kit (with AMD providing those companies compensation. (The last seems unlikely, sure, but it's a method by which using your old cooler doesn't cost you money as the end user and it doesn't compromise performance of the chip in any way the way screwing with its cooling system or possibly its mounting system would.) The only logical reason I can see for the thick IHS is if they've got plans for the next generation to be using some architecture that's going to use that extra space for something more productive than a copper slab. Maybe slip a layer of cache underneath the processing chips as an extension of the experiment they were running with the 5800X3D? (I don't know CPU architecture well enough to know that's remotely reasonable, it just seems like shackling yourself to having a thick slab of IHS is a weird choice unless there's plans to use that space for other stuff in the future)
@@fist003 more like they want to have some 'upgrade' for the Ryzen 8000 series. Theyll sudden have lower temps and better performance all due to a shorter IHS and nothing else.
@@fist003 My point was there were other ways to achieve that without compromising the ability of all users to cool their CPU without doing things that would void the warranty (lapping/delidding). Especially since they've comitted to usng AM5 for several years, so every AMD processor for the next several generations will have to deal with this thick IHS issue. Again, unless they're planning to use the vertical space in future designs Which I have no idea is even remotely reasonable.
On intel 12th gen right now, if I had this in a system, I can't justify voiding the warranty for 100mHz gain and 5c cooler. Interesting finds though! Love the video.
I believe it was 10c from 94ish 95c stock down to 84ish 85c at the end. But yeah, this will always be for us few that are willing to do anything and everything to get the absolute most performance out of a beast cpu. I'm really looking forward to the de-liding tool honestly. Derb8er dropped I think 20c+ from doing so
@@KobraTrading for 20c you would definitely need a good cooler if you don't have one already and very good thermal paste, the reason for this is that stock the cooler doesn't make as much of a difference because the cpu is tuned to go to that temperature at stock
The funny thing is that before about 2008 they were exposed silicon with the cooler right on top. They then started putting 'heat spreadders' or IHS on the top.
Well that rules out new Ryzen for my upgrade. I live in western Australia where summer is over 40c ambient and anything putting out that amount of heat will make me pass out after an hr in my room.
I know you’re not going to see this but I tried the Kingping extreme, Arctic MX5 and now Kryonaute extreme on my 7950x and nothing can drop it even 1c and all cinebench are within the same results at 38100 -/+ 50
i removed a fair bit off my 5700G and i got some pretty awesome results. allowed me to get 4.7ghz all core stable without going nuclear. before it wouldnt even come close. instantly shot up and crashed haha!
On derbauers conductivity test showed amd's nickel coating was pretty think and was decreasing the w/mk so taking it bare copper might help a little on top of improvement from better contact.
Yes, I find it hard to comprehend why thinner copper helps when all you're doing is bonding it as best you can to another block of copper. I thought more copper = better. Except if you grind off the nickel and make it really flat you're making a better copper to copper contact area.
@@wayland7150 shorter distance the thermal energy has to travel the more efficiently it can keep the chip cool, direct die cooling takes this farthest.
No hoodies esp ones with strings near rotating machinery type... No ties , no wired headphones , no loose fitting shirts .. You can imagine why. Little sander like that youu would likely stop it with a body part ...but would you want to?
I got to get this out of my system: This is not lapping. It is at best percussion sanding. Lapping specificly uses a solid base, and an abrasive compound between it and the work piece. Also one thing I would love to see is someone lap their CPU to their cooler. As you can lap stuff so they mate perfectly together.
@@zbrkesbris5987 yup wringing them together. I would also love to see someone try that. Though I'm not sure it would work with the mounting pressure needed with landgrid array processors. As the IHS may flex.
It was mentioned before but just to put my *2cents* in ... use a figure 8 motion when lapping. As a millwright, when we are lapping the surface of a turbine, for the cover, we use this motion. You don't need high pressure steam escaping.
You can get pretty thick (8-10mm) float glass plates for ~$20 off that AtoZ site. In sunlight, find the side that has a rainbow shimmering effect, that's the side that was floating on the molten tin. Mark it with a permanent marker and use the other side for lapping. I'm still using the glass I had to special order from a glass shop 20 years ago to lap Barton dies!
@@fluphybunny930 Not worth it to you, risk is in the eye of the owner. That said, I wouldn't have bothered with it either given just how thick these AM5 Ryzen IHS' are. Direct die and lapping the die is where I would go. My advice still applies to lapping in general... not everyone here is on the bleeding edge AMD or Intel platforms. I lapped the IHS and the die(s) on a 3800X and using LM dropped temps 10ºC on my WC setup. I kept the IHS because of the offset chiplet layout. That proc is now air cooled and doing fantastic for my freind I gave it to after going to a 5900X, and it too will be getting the same treatment.
If amd broke cooler compatibility people would’ve complained that not only do they have to buy new ddr5 ram, thru also have to get a new cooler or a bracket (that may have been sold out for weeks). They can’t win.
so happy to see something we were messing with on forums 15 yrs ago finally showing up in the mainstream... add to cart.. done haha. honestly for most people this is all you need to do... de-lidding will give better temps with a properly mounted waterblock but its just such a time consuming fuss to get that mounted properly... many remounts and trial and error. with an ihs you don't have to be that careful. just be sure to do the same to the cooler you wish to mount.
It’s a bit early for now. He’s already shown that the CPU is the bottleneck for 1440p and 1080P with a 7950x. Until a better CPU comes out, everything else is the bottleneck.
I'm no where near hardcore enough enough to do something like this, but it's fascinating. I simply am the OC'er who tinkers with bios following OC guides for my CPU and happy to see a small bump in performance with no loss of stability and I'm satisfied. I live in a hot home in Florida with people who don't like to use AC so i feel like i need a lot of headroom to account for huge temp flux in room temp and so running an OC at it's limits of stability would likely not work in my environment. I don't think I've ever OC'ed AMD and plan to go AMD this time, will be fun to learn the AMD tricks that differ from intel.
the nanosecond i heard beltsander is 120 grit i knew jay is gonna overdo it. 120 on a belt is like a lazer. it TEARS through stuff. at most go 360 so you got good control
Technically, I think a lot of scratches, and actually scratches no just cosmetic imperfections, would actually improve performance. It's exactly why radiators are the design they are, inner part of the cold plate in contact with the coolant has Micro fins. Scratches make more surface area than flat, which means more contact surface to transfer a larger amount of heat. BUT, that's assuming you have an appropriate viscosity of TIM, and actually fill all the Micro valleys.
I am 55 years old I had done this on a processor a pentium of what I remember, to run it in an ASETEK case at the time Vapochill case with phase change with negative temperatures 😄For a frequency that would be ridiculous today 😁I have never sanded a CPU since, I still have this Vapochill case with Windows XP and the pentium. I have not relaunched it for a long time but sanding remains relevant as far as I see 😎
Jay, I learned the other day there is a much better way to go to the BIOS instead of smashing the DEL key like a madman, using the shutdown console command. shutdown /r /fw /t 0 The /fw modifier tells the system to enter the BIOS directly when it reboots. Make it a shortcut on your desktop and profit.
You can polish lid. I have done it every time i shaved down a cpu. polish doesn't leave some kind of protective barrier on metal, just use 99% alcohol and clean it thoroughly.
I think AMD made a mistake by trying to be backward compatible with AM4 coolers, should have had a thinner IHS and just let the cooler manufacturers figure that out.
Thanks for another great video, Jay. Just wanted to share this. I have a 7600x (liquid cooled, Gigabyte B650 board) and can achieve 5.45 ghz all core @ 75~80 deg C using PBO negative curve offset and +200 on boost. Power settings are "eco mode" (88 watts max). 5.5~5.6 ghz single core. These are amazing cpus if you understand settings and have good cooling. I'll be lapping this week as long as the standoffs allow it.
If you want to lower temps, then lower your boost limits, or set a constant overclock with lower voltage. You can probably do an all-core overclock of 5.4ghz at about 1.275V
2 things... the type of glass you want for lapping is float glass, most non-cheap glass is float (table tops, windows, mirrors, ...) You also really need to not launch metal dust at your server.

It's honestly amazing how much of a difference sub-millimeter tolerances make. I'm so happy I don't deal with anything that precise.
Well a mm is pretty big actually. Even cheap FDM 3D printers (setup correctly) typically have a repeatable tolerance below 0.3mm. Above that starts becoming a problem more than you might think. Sub 0.1mm (100um) is where it gets tricky and typically where a lot of professional machining is.

Also, if you polish the CPU and the heat transfer block until they physically bond, you will get the best heat transfer. It is pretty cool to see two pieced non-magnetic of metal act like they are magnetic. Looks Great!
I know Jay is supposedly OG, however he sure didn't look like he knew what he was doing. Crappy semi-tutorial.
Jay is just O without the G 😅
Prior machinist and folding knife Maker here, you should never lap with the power sander. When you're lapping a cpu or anything else you want it to be flat and parallel. Using a sander, no matter how flat your platen is, putting too much pressure on one side will cause it to no longer be parallel. Using a surface plate and a figure 8 pattern while turning often is going slowly is your best bet of staying flat and parallel. Yes it takes much longer but precision always does And I wouldn't trust using a surface grinder on a cpu or IHS
That'd be one expensive projectile on a surface grinder 😅
Jay, First thing i was thinking
I want to polish it 😋😁
For future reference, a figure 8 pattern instead of circles when sanding makes it much easier to keep it flat
9:30 Polish is good when the IHS and the cooler cold plate are polished, it will literally create a 0 gap suction.
It's cool that delidding is back in style with these cpus. I delidded my old 8700k, and that turned out to be tons of fun, having the fastest cpu on the block. I sorta won the silicone lottery wirh that, managed a 5.3 all core.
You risked a good CPU and were rewarded with great success. 5.3 GHz is amazing.
Mine did 5.3 at 1.3v before delid :) it's the only golden chip I have ever got.
This Old House meets Jaystwocents, didnt thing Jay would break out the super high-tech gear to modify the 7950, hilarious.
Looking at that huge ass heatspreader i'm definitly gonna delid it when i get mine next week. I think it's the best cpu to do that with. Derbauer got 20C. Lapping just seems to be more work than delidding for less temperature gain.
did you find any tool for deliding? Debauer's one isn't released yet apparently.
@@alext9558 No, actually i'm still waiting for my custom waterloop. I just have an AiO now so i don't delid yet.
But temps are good enough. Though i had to limit cpu to 80C + slight undervolt and it only reaches ~5.1 then which is still blazing fast. Stock 7950x reaches 95C+ very quick. I feel sorry for the users who get this and have no idea about bios and customizing.
I'll try to overclock it to 5.7 when i get my loop.
@@jx4219 same here, waiting for my case since last month, I think I'm gonna go down the lapping road as I want to delid anyways at some point. Cheer!
Im waiting for the 3D variants to come out and yea AMD really fucked up with this IHS.
personally gonna just lap it since that feels safer to me and I dont need any extra tools or parts for it. I can just 3d print the holder for it for lapping
As a metal worker, when you are lapping you should do it in a figure 8 motion.
If you’re going to go for gold and void warranty it feels like a delid and mount swap would be the best way to go. Lapping seems a lot of work for a halfway result.
problem I can see with that was how hard it was to get the mounts set up. Not sure if he was at the limit of what he could do or not. Personally, to save the 5-6 C I think it would be great as long as I could get a cooler on it. I know 5-6C isn't much but that was from pushing danger zone into more comfortable territory.
Well, lapping is marginally safer as long as you don't try to lap the max amount of 1.2mm. say, go down by 0.8 to 1.0mm.
With delidding, one can easily damage the substrate and/or dislodge one of the caps.
Lapping is still a significantly lower risk of outright killing the CPU compared to delidding. Honestly for what it can do I'd consider it a worthwhile mod for somebody interesting in a heavy OC, but doesn't have the money to spend on a second CPU if one dies.
@@readypetequalmers7360 Sanding something perfectly flat isn't easy
Jay, if you use a figure "8" motion it will make it easier to get a flat finish. Circular motion leaves point in the middle. Back and forth leaves a ridge across it. Think of it this way, the direction you move it digs in on the forward moving face/side. Push it north and the north end digs in. Same theory why Brembo brakes often use smaller disk puck on one end of the pad.
Terry from Australia.
You know they make concave mirrors for telescopes using the same technique as Jay is using for a flat surface except they using a particular grinding motion. If you do it wrong you can end up with a convex or concave surface.
Even with the lapping, it's crazy how much heat is pouring out of that CPU. I remember it wasn't that long ago we only needed a 120mm radiator to deal with a CPU, and now it seems that 360mm of radiator won't be enough when talking about the long gaming/ intensive software sessions. Great video!!
appearently you don't... according to hardware canucks' testing the 7950X does perfectly fine even under a 120mm tower cooler. The whole cooling issue seems a bit overblown by Jay.
@@cosmic_cupcake i mean "perfectly fine" is subjective with this series of CPU's because they are designed to keep in the range of 95 C. So yes you can cool the chip with anything, but the performance you get will change drastically if it has better cooling. It will always try to hit 95 C and throttle if you exceed that limit. "Perfectly fine" does not mean what it used to mean for previous generations. I think I remember just fine.
If you wanted to measure the gap between the cooler and the CPU I suggest using plasti-gauge.
Works for engine bearings, would work great for that!
Loving these longer vids you've been pushing out recently! Gold stuff!
This was what i wanted to see. I know lapping and delidding both void the warranty but I'm more willing to lap than i am to delid.
Exactly what i was thinking of
We'll soon learn how much more de-lidding gets us. I bet i's not really worth the risk. At least with lapping you approach the danger level slowly and can stop.
@@wayland7150 According to der8auer, it's 20° Celsius (along with lower power draw)
@@wayland7150 We kind of already know the results. Confirmation never hurts though.
That's interesting because I'm more willing to delid, It is much easier. Getting a perfectly flat surface lapping is way harder than people think. I've delidded and it's very easy running a thin knife through the glue.
This reminds me when my roommate and I would polish our Pool Cues. The final sanding we did with glass bottles. Soo nice and smooth!
Boys will be boys.
Next time you replace the belt grinder you should get one that has the vertical disc plate grinder and rest plate. Makes that job a whole lot easier. 👍
also one that has a tension arm for sand paper
@@bouzoukistudent8180 The one I got has the tensioner built into one of the belt roller guides...I think most half decent ones do.
I just gained the courage and lapped the IHS on my 7950x3d. Didn't go down to far since I don't have the Thermal Grizzly product to help. So a half degree difference but noticed my computer was much quieter during gaming. Before it used to scream to keep it normal temperature ranges. Keep doing this type of content!
It would be interesting to do with with a proper mill. Something that could guarentee precision and levelness.
See if der8auer will mill an IHS on video. :^)
I love how you coop with Roman on that. Actually i mostly watch your channel, his channel and steve´s.
thats actually interesting how cpu doesnt go in contact with aio when you sand it down thats like few milimeters
The thickness of the CPU was to make it compatible with AM4 coolers
Welcome to mechanical engineering. When stuff has tight tolerances, even a millimeter makes or breaks everything
The hook and eye mounting system would probably be OK without modification. It's spring loaded and only the CPU holding the cooler up.
I'm not convinced the thickness reduction is what worked, rather the better contact surface.
@@TheBlueBunnyKen And in turn hurts thermals a lot. Would be much better for AMD to just raise the socket/make it thicker tarher than the CPU.
@@LEXXIUS agreed
Retired Machinist here... if you want a flat serface from lapping you should use figure 8 motion instead of circular motion.
The last CPU that I have ever seen a UA-camr do direct chip cooling on was a 7700K by Linus Tech Tips and the results were amazing.
DerBauer does this quiet often.
@@L1ft0ff Yeah I know. I was thinking of a video that I have seen from a UA-camr that I watch frequently.
you people make me laugh when you say "Oh no the warranty" like, for a processor you gonna overclock to hell? lmao
AMD/Intel can't really tell if the CPU was killed from overclocking. So yes, it's better to have the warranty even if you overclock.
I can't wait to see what Zen4c/x3d can do next year. When they tame the temps and power on that it's gonna be amazing.
No plan to tame temps. The high temps of 7xxx are they intentional.
Zen4c is an EPYC CPU though no?
@@vgernyc it's just the code name for the denser node with more cores. It's not specifically epic it'll also be used in threadripper. There's also a chance they could use it as a last ditch effort if intel catches up because it's double the density so if they somehow wanted to shoehorn more cores on am5 before they drop Zen 5 that would be the way they could do it. They also kind of hinted at the fact that it would be double the cores for the same power which is why I think they may actually refine this. I didn't mean to imply that they're going to somehow drop some weird core revision of current zen 4 that's going to quote, tame the power. They are not doing that. Zen 4 3D and Zen 4C are indeed supposed to be further refinements on the same node so there is a chance they will not run quite so aggressively hot, and I feel like if they have a chance to reign that in a little bit why wouldn't they. They clearly pushed Zen 4 as hard as they possibly could to make sure they stayed ahead of raptor lake, or at least extremely competitive with it.
We were told it was a voltage issue, bit power/temps. Yes, they are related, but there you go
@@pdamasco As long as AM5 CPUS are compatible with AM4 coolers the temps will be 10c higher than they need to be.
“I’m not Flat right now”
Best quote from Jay
Have you ever tried lapping the cooler and IHS together with lapping compound? They mirror each other's shape if you did.
I think Im going to do this as well, but i started wondering if there is a way to seal around the edge of the IHS to prevent anything from getting underneath during the lapping process. The thought of copper contamination under there doesnt sit well with me, and theres realy no way of knowing 100% if you've cleaned it all out afterwards. Im not sure what materials would be safe for this job, but the 1st thing that came to mind was some sort of clay as i would assume it should be safe when in contact with the SMDs around the edge of the ihs. I also considered a small bead of hot glue as that stuff always pulls away cleanly once dry, and would be more robust than clay, though im not sure if it would be too hot for those SMDs, or if it would let go of them and not pull them off at removal time (probably not, but nothings impossible). I dont think tape would seal well enough, so thats out, and thats about where i ran out of ideas. Anyone else have any thoughts along these lines?
hey jay i realy love these experiments to see the temp diferences. but i would like to see if there is an difference with lapping with sanding paper vs good enough whetstones. you can even polish it with an extremely high grid to smooth out the height difference as with sharpening knives. and to get an perfectly flat stone you have flatening/maininance stones to make the whetstone flat(if that is anny concern at all)
I love my 7900x ! i just got it up and running last night with 64gb of ram, 4 DIMMS working at their rated 6000mhz ! I applied some tweaks to the Precision boost overdrive in my Asus board and managed to unlock sorcery that made my CPU run cooler with less power draw and still maintained my performance. I ran one pass on Cinebench R23 multi core and got 27995, and my CPU did not exceed 52c for the entire run, i have a Noctua D15s with its stock fan. This thing runs cooler now than my 5800x did.
You could have easily exceeded 95 C using the belt sander. Wet sanding is your friend when trying to remove metal or plastic! (I have the same sander and can easily melt PLA from my 3 D printer if I get too aggressive.)
"if you get too aggresive" bro PLA already melts at the SIGHT of the belt sander xD
he used wet sanding after sanded off excessive material.
I'm glad Jay's a car guy being a diesel mechanic my self I was thinking of polishing I understand the insulting aspect as well so that's a no no but would be interesting if u could cnc mill up to 1 micron error then it would be perfectly flat with no valleys or peaks from scratches
Jay figuring out you can reuse original hardware is the gem of info in this video. So flippin cool
Edit: Hey since you were able to get the z axes height lower with the original hardware, couldn't you take more off the ihs now?
2 years in having a 7950x and ive opted to just lapp my cpu vs upgrading. At stock I was getting your r23 score of around 38k after you lapped. With tuning I can easily go over 40k, so with more thermal headroom I can make my chip an absolute monster.
Would be interesting if you go to the lowest lapping possible before you delied it. :)
13:32 Even the experts!!
Jay you shoulda gone all the way and showed us the 1.2 mm result. I was hella curious what you’d get, and without reality to settle me down, I keep wondering “what if it would have dropped 10-15 degrees if he went that last .4”….
It’s not going to drop another 10-15 like that, probably 5 C is realistic and 10 is very generous. Direct die only takes about 20 C off so this would have to be less than that
Yeah do not expect miracles from another 0.4mm, but at least he did the test and seeing results for me at least totally worth it, as lapping still has protection for the die, and you shave off like 10-15degrees which is a big improvement from 95, realistically speaking no cpu will run full tilt, but reducing temps increases significantly cpu life and gives extra performance
Might as well go all the way imo. I would not do it without delid first though.
Igor's Lab did some testing of the 7950x vs th 5950x. The 7950x produces about 20w more heat and runs about 9C hotter. I would bet that going down to the same IHS thickness as the 5950x would get you about 8-9C lower than the stock 7950x IHS.
@@alexmills1329 The autism lvl of AMD is is 10/10, that we have 95c temps instead of 85c because they wanted to make it AM4 cooler "compatible"
Linus Tech Tips said in their "We killed it... but then SUCCESS!!!" vid that you DO want scratches, but that was when they delided the CPU and were lapping the actual DIE itself so they could liquid metal it which is obviously way better than regular goo and probably means that large scratches don't make nearly the difference that they would if you were using regular thermal goo. Am I wrong? Is there more too this?
I lapped the IHS on my 3900x and I used sharpening stones for knives and even went down to some special hyperfine grit paper of 300,000 grain, I made that IHS the smoothest thing I had ever touched, like actually haha. No polish used. Didn't really notice a huge difference in the thermals lol. A degree C was about all I got.
Awesome video Jay 😁 nice to see AMD show up to the table as far as cpu speeds go
Yeah now if they could only find a way to educate the masses into understanding measuring a few MHz in cpu speeds is a fools errand and far less important than other factors.
I'd expect tempered glass that thin to bow really easily. A 9x12x2 granite surface plate is like $60 on Amazon. Certified flatness to 0.0001" (0.0025mm) If you lap cpu and cooler both with that plate you should be able to get them to the point where they'll stiction together.
I have to admit, I am still surprised that AMD decided to go for a thick-as-heck IHS as its solution to AM5 processors being shorter than AM4. It seems like it would be much more reasonable to do any of the other 3 options I can think of:
--Raise the whole mount on the socket side, such that the chip just sits higher
--Put out specs for what the new height target is and work with as many of the big names in coolers as possible to help them have brackets ready to adapt their current hardware to AM5 on launch day
--The above but also set up deals with those cooler manufacturers such that anyone buying a 7000 series processor gets a code they can use to get a free adapter kit (with AMD providing those companies compensation.
(The last seems unlikely, sure, but it's a method by which using your old cooler doesn't cost you money as the end user and it doesn't compromise performance of the chip in any way the way screwing with its cooling system or possibly its mounting system would.)
The only logical reason I can see for the thick IHS is if they've got plans for the next generation to be using some architecture that's going to use that extra space for something more productive than a copper slab. Maybe slip a layer of cache underneath the processing chips as an extension of the experiment they were running with the 5800X3D? (I don't know CPU architecture well enough to know that's remotely reasonable, it just seems like shackling yourself to having a thick slab of IHS is a weird choice unless there's plans to use that space for other stuff in the future)
they mainly just want backward compatibility with existing coolers
@@fist003 more like they want to have some 'upgrade' for the Ryzen 8000 series. Theyll sudden have lower temps and better performance all due to a shorter IHS and nothing else.
@@fist003 My point was there were other ways to achieve that without compromising the ability of all users to cool their CPU without doing things that would void the warranty (lapping/delidding). Especially since they've comitted to usng AM5 for several years, so every AMD processor for the next several generations will have to deal with this thick IHS issue.
Again, unless they're planning to use the vertical space in future designs Which I have no idea is even remotely reasonable.
Jay reminded me a little of "Tim The Tool Man" Taylor from Home Improvement with how he lapped it with a belt sander instead of by hand as was meant.
On intel 12th gen right now, if I had this in a system, I can't justify voiding the warranty for 100mHz gain and 5c cooler. Interesting finds though! Love the video.
I believe it was 10c from 94ish 95c stock down to 84ish 85c at the end. But yeah, this will always be for us few that are willing to do anything and everything to get the absolute most performance out of a beast cpu. I'm really looking forward to the de-liding tool honestly. Derb8er dropped I think 20c+ from doing so
@@elkomander3510 with a tool, and for 20c, i WOULD do it.
@@KobraTrading for 20c you would definitely need a good cooler if you don't have one already and very good thermal paste, the reason for this is that stock the cooler doesn't make as much of a difference because the cpu is tuned to go to that temperature at stock

Cool, I will go for it with direct die, I did it on a 9900K, and it made a 20 deg C difference. Just amazing, but of course, very risky for sure.
The funny thing is that before about 2008 they were exposed silicon with the cooler right on top. They then started putting 'heat spreadders' or IHS on the top.
I have a 9900k and will go for Raptor Lake tomorrow for the 13900k and not have these problems it will go to 5.8ghz and 32 threads

On derbauers conductivity test showed amd's nickel coating was pretty think and was decreasing the w/mk so taking it bare copper might help a little on top of improvement from better contact.
Yes, I find it hard to comprehend why thinner copper helps when all you're doing is bonding it as best you can to another block of copper. I thought more copper = better. Except if you grind off the nickel and make it really flat you're making a better copper to copper contact area.
@@wayland7150 shorter distance the thermal energy has to travel the more efficiently it can keep the chip cool, direct die cooling takes this farthest.

You can imagine why.
Little sander like that youu would likely stop it with a body part ...but would you want to?
I got to get this out of my system: This is not lapping. It is at best percussion sanding. Lapping specificly uses a solid base, and an abrasive compound between it and the work piece.
Also one thing I would love to see is someone lap their CPU to their cooler. As you can lap stuff so they mate perfectly together.
and if they are both near-perfectly flat - they could bond together removing the need for thermal compound inbetween
@@zbrkesbris5987 yup wringing them together. I would also love to see someone try that. Though I'm not sure it would work with the mounting pressure needed with landgrid array processors. As the IHS may flex.

@@toseltreps1101 no, not this. Im not being 20-20 hindsight smart. Im telling other people who might want to also try this. ie myself.
It was mentioned before but just to put my *2cents* in ... use a figure 8 motion when lapping. As a millwright, when we are lapping the surface of a turbine, for the cover, we use this motion. You don't need high pressure steam escaping.
You can get pretty thick (8-10mm) float glass plates for ~$20 off that AtoZ site. In sunlight, find the side that has a rainbow shimmering effect, that's the side that was floating on the molten tin. Mark it with a permanent marker and use the other side for lapping. I'm still using the glass I had to special order from a glass shop 20 years ago to lap Barton dies!
Except it clearly isn't worth the time effort or warranty.
These CPUs just don't give enough extra verse the risk.
@@fluphybunny930 Not worth it to you, risk is in the eye of the owner. That said, I wouldn't have bothered with it either given just how thick these AM5 Ryzen IHS' are. Direct die and lapping the die is where I would go. My advice still applies to lapping in general... not everyone here is on the bleeding edge AMD or Intel platforms. I lapped the IHS and the die(s) on a 3800X and using LM dropped temps 10ºC on my WC setup. I kept the IHS because of the offset chiplet layout. That proc is now air cooled and doing fantastic for my freind I gave it to after going to a 5900X, and it too will be getting the same treatment.

Great video Jay!!
If amd broke cooler compatibility people would’ve complained that not only do they have to buy new ddr5 ram, thru also have to get a new cooler or a bracket (that may have been sold out for weeks). They can’t win.
so happy to see something we were messing with on forums 15 yrs ago finally showing up in the mainstream... add to cart.. done haha. honestly for most people this is all you need to do... de-lidding will give better temps with a properly mounted waterblock but its just such a time consuming fuss to get that mounted properly... many remounts and trial and error. with an ihs you don't have to be that careful. just be sure to do the same to the cooler you wish to mount.
just want to add, those were still not right things, theyre consumer rights, forcedly, violated
Any plans for videos comparing CPU bottlenecks of the 4090?
My 5900X runs at 4.95Ghz single core I don’t see 99-100% GPU very often on the 4090 at 4K
It’s a bit early for now. He’s already shown that the CPU is the bottleneck for 1440p and 1080P with a 7950x. Until a better CPU comes out, everything else is the bottleneck.
I'm no where near hardcore enough enough to do something like this, but it's fascinating. I simply am the OC'er who tinkers with bios following OC guides for my CPU and happy to see a small bump in performance with no loss of stability and I'm satisfied. I live in a hot home in Florida with people who don't like to use AC so i feel like i need a lot of headroom to account for huge temp flux in room temp and so running an OC at it's limits of stability would likely not work in my environment. I don't think I've ever OC'ed AMD and plan to go AMD this time, will be fun to learn the AMD tricks that differ from intel.

Technically, I think a lot of scratches, and actually scratches no just cosmetic imperfections, would actually improve performance. It's exactly why radiators are the design they are, inner part of the cold plate in contact with the coolant has Micro fins. Scratches make more surface area than flat, which means more contact surface to transfer a larger amount of heat.
BUT, that's assuming you have an appropriate viscosity of TIM, and actually fill all the Micro valleys.

Incredibly interesting video and I look forward to your de-lidding video.
Jay, I learned the other day there is a much better way to go to the BIOS instead of smashing the DEL key like a madman, using the shutdown console command.
shutdown /r /fw /t 0
The /fw modifier tells the system to enter the BIOS directly when it reboots. Make it a shortcut on your desktop and profit.

You can polish lid. I have done it every time i shaved down a cpu. polish doesn't leave some kind of protective barrier on metal, just use 99% alcohol and clean it thoroughly.
I think AMD made a mistake by trying to be backward compatible with AM4 coolers, should have had a thinner IHS and just let the cooler manufacturers figure that out.
Thanks for another great video, Jay. Just wanted to share this. I have a 7600x (liquid cooled, Gigabyte B650 board) and can achieve 5.45 ghz all core @ 75~80 deg C using PBO negative curve offset and +200 on boost. Power settings are "eco mode" (88 watts max). 5.5~5.6 ghz single core. These are amazing cpus if you understand settings and have good cooling. I'll be lapping this week as long as the standoffs allow it.
Could i ask some how much negative did you set
@@nhacspicy6444 PBO voltage offset is -30. I don't know what that actually equates to in Volts, but that's the max setting and my CPU does fine.

@@nhacspicy6444 70-80 is perfectly fine. It's about the same for mine with a custom water cooling loop (two rad system).
