Updated pads on both sides and added thermal compound on the metal part that touch the heatsink in a front since it has nothing there. Now I'm getting 123.1 MH/s with Vram at 90C. Room temp is around 26C
Nice! I have managed to keep the temps at 92C and get just over 120 MH/s with the 3090 @ 305W with an ambient temperature of 76F. I may be able to push it some more but I think I am tired of messing with it for now. I may try changing out the 1.5mm pads out for thinner ones and use the liquid metal for the GPU, but I need to get something to coat the surrounding area to protect it if something spills if I use too much. Thanks for sharing your results!
Best results I have had for my OMEN so far is 116mh using t-rex miner with hiveon pool. I have replaced the thermal pads with 1mm minus pad and added heat syncs and a fan. Open case and the room temp is around 65f. I'm running 85 on power,-275 core, and +650 on the mem clock.
THANK YOU SO MUCH! made about a 20C difference on my card (which is hard to believe!) downclocked -502 Mhz memory and Core 70% power was hitting 96C, after using a 1.0mm thermal pad on the back and some thermal paste on the frame on the front, three heat syncs on the back of the card and a fan went down to 70C when downclocked! Turned it up to -100 +500 and 90% power and was at 82C with my case open and 88-90 with my case closed getting 113MH/s! Before the Mod I would max out at 110C and it would throttle.
You are the man. I put the 3090 in my main PC. Because of the ~22 MM between the backplate and CPU cooler, I used 2 Noctua slim 14mm fans on top of a bunch of little 5mm heat sinks. I also put paste on the copper plate that makes contact with bracket in the middle of the card - sorry don’t know the technical name. Anyways, 20 DEGREE REDUCTION. Didn’t even change the thermal pads yet; waiting on Amazon. Oh, I did add some extra paste to where the copper contacts the GPU chip. One more thing...I put little heat sinks on the narrow border portion of the card facing outward because it also gets hot. Any way to upload a picture on here? First UA-cam comment ever!

Cool. I actually have my second almost exact same spec omel 30l with 3090s. I have one card taken apart already waiting for my thermal pads and compound and the other computer arriving Thursday. I could only mine around 95-100mh/s as well so I'll be able to get an exact comparison when I get my new comp.
I did mine and with the case side off I get 110-120MH/s at 102°C to 106°C (215°F to 222°F). You can use 1.5mm thick pads on the back plate, but the GPU side seemed to be quite tight on tolerance, I used 1mm pads there after having a bad time with 1.5mm pads. I also used Thermal Grizzly Kryonaut on the GPU itself which gives much better GPU behaviour. The biggest problem is back panel cooling, that's where heat just accumulates, so getting a heatsink and fan even just placed on top of the back plate is essential, and any extra intake you can do through the bottom of the case is definitely a good idea. I'm thinking about modding the front of the case to add an additional fan above the RGB Cooler Master one to provide direct intake airflow over the back of the GPU, it really needs it. EDIT: put thermal compound between the frame the VRAM chips are cooled by and the actual copper heat block! I got down to 90-92°C constantly at 85% fan speed whilst mining at an average of 117MH/s this way!
I would say you need some paste or pads between the heat sink and BP for shure. You have to transfer the heat to the heat sinks, so a pad required I want to do this later too ...

Thank you! My Omen 30L with a 3090 is being delivered next month. Can you do another video of how you put the heat sink together with the fan on the back of the 3090 and what headers you used to connect it to the MOBO?
The motherboard doesn't have any extra fan headers to add more fans, so I had to use the one located under the graphics card next to where the USB 3.0 connection to the front panel is made. I used a fan splitter to add additional fans (a link to the one I used is in the video description). The heatsink is being held on by thermal pads and gravity, so I didn't have to modify anything else. The fan is just resting on top of the heatsink.

Bro by putting thermal pad you void the warranty of the expensive card. My solution put a strong box fan like a Vornado air circulator in front of the card.

I managed to overclock the memory +1500 and still maintain temps under 90C with a hash rate of about 100MH/s. There are no VRAM chips on the back of the board either, so it was a bit easier to swap them out.
Great video. I just bought the OMEN 30L (i9-10900k/3090) because it's the easiest way to get a 3090.

@@jimbob9086 Thank you for the info! I don't plan to mine on it (gaming and AI software dev), so hopefully the performance will be solid. Any other issues with the HP cooler compared to the founders?
Would love to see where the thermal paste was applied. I did the mod but not have a hotspot that shoots up to 104 instantly and throttles. VRAM Memory temp appears to be doing alright. Not sure if my issue is on front of card or because I covered most of the copper like in the video description. I did use 1.5mm pads.......
The 1.5mm pads are a bit too thick and makes it hard for the GPU die to make contact. You can try squishing the thermal pads to help, or replace with 1mm pads.
Hi, nice video, thanks. I orderd the thermal paste, my memory is hot too on this card (I have the same HP RTX) but I'm gaming with a VR Glass with this card :-) want more cooling
Did you remove the top plastic layer from the backplate to attach that additional heatsink and fan? Does the plastic layer come off easily and can it be attached back afterwards?
I didn't remove anything from the backplate and didn't notice a plastic layer, besides the RTX label. I just used some thermal pads to stick the heatsinks directly on top of the backplate.
I removed the fan and heatsink to test their impact on the VRAM temps. Ambient temp is 75F and mining at 120MH/s at 305W, without the fan / heatsink the VRAM temps are at 96C. With only the fan the temps dropped to 92C. With both the fan and heatsink, the temps dropped to 88C.
Nice video! I have the omen 3080 having the same issue. If I don’t change the thermal pads, will the heat sink and fans be enough to help? Can I have the details to the fan and heat sink you used? I am assuming it’s radiator fan you use blowing upwards?
@@RandomGreenFishPhone Hello there I have a model which is 3080. My Afterburner settings are as follows. -power limit 65% -clock -100 -Mem +1000 -Fan 90% I got 91 mh rate. Junction heat is 106 celcius. When I set up the power limit 70 junction heat increase 108-110. I guess it's the most logical option to keep the power limit at 65. 106 junction good value for mining?

@@sneekeeboi I have another fan at the bottom of the case by the power supply to try and improve the air flow. If you only want to add 1 more fan then a 2 way splitter is fine.
I did this with the 3080 in my Omen PC. I used Gelid thermal pads (as they where available). The 2mm was way to thick, so I used 1mm. I also replaced the GPU thermal paste and added paste to copper contact area's. This gave amazing results for my VRAM. My core temps are now about 8-10 degrees higher, which is weird. I reapplied the pase (a bit thinner), which made no difference. Then I added a 1mm pad on the back of the GPU core, this still did not make a difference. I wonder if I need to add a thicker pad between the GPU and the backplate.
@@THEMANZ6 I opened it up once more to take a look. Closed everything up (a bit tighter this time) and tested again. Still some weird core temps. Shut the system off and let it sit overnight. The next day everything was great, and has been up to this day. I can't really explain what happened. Maybe the pads expanded the smallest of amounts and made better contact.
Better results than I got 😆 still can't figure out why I'm getting a bios error for the card after redoing the pads and paste, though I did use the 1.5 mm thermal right pads and it does seem like the 1mm would be a better fit for how much compression there was. Used mx-4 paste as well. 🤷♂️ I've taken it apart a handful of times now and tried to figure out if I did something wrong but everything looks good - Even so I appreciate the content and the learning experience.
The first time I put the card together with the 1.5mm pads I didn't have everything tight enough to fully squish the pads so the processor and the copper plate weren't making full contact, resulting in extremely high core temps. Maybe the same thing is happening with your card and the temps are so high the bios is shutting things down.
@@RandomGreenFishPhone I thought that at first but it's a post error, no blank screen or anything, just immediately beeps at me 5 seconds or so after boot. I have one more theory to try and after that I guess it's rma.
@@alexheath7856 Weird... The only time I heard my computer beep during boot was when I forgot to plug in the power to the graphics card. Sorry I can't be more help, but please let us know what you do when you fix it.
@@RandomGreenFishPhone will do, I did not see an LED light anywhere external or internal but 3 low tone beeps and 3 high tone translated to the LED code is not detecting graphics card - took a minute to piece that together on HPs site. If I get it figured out I will post again incase others have the same issue.
@@RandomGreenFishPhone It happens to me as well. The 1.5mm on the front of the Hp rtx 3090 card will elevate the cooper plate so more heat resistent from the die to the plate. It results in temp rise instantly to 100C when underload. Changed to 1mm and it immediately fixed the problem. After playing with it for a week, the black metal frame in the hp rtx card is mainly what causes this sensitivity problem to the thermal pads. You want that metal frame to be as close as possible to the GPU circuitboard so 1mm or even less than that would be better. I tried modding all situation, from having all the thermal pads on all parts of the circuit board, to the VRAM only, and it DOES NOT improve the temp significantly. Should keep in mind that the thermal pad is to fill the gap so the two surfaces make contact for heat transfer, it actually resists the heat if adding the thickness. I have seen a lot of people using the thermal pads as a holy grail to having more heat transfer. As an engineer, I can say that it is not. But in fact, you want the thermal pads to be as thin as possible and just enough to make contact with the two surfaces. Good luck.
interesting that this happens on a 3080 as well as 3090, and not a HP model as well, at least that rules out any kind of manufacturing defect unique to the custom HP 3090
Sorry, I haven't come across a 3080 used in the HP Omen. It appears that manufacturers are using anywhere between 0.5 - 3mm depending on the fan and heatsink design. You may want to open yours up and measure the thickness of the existing pads first, or buy various sizes if you want to avoid opening it up more than once.
@@starkillertoy Simply opening up the card should not void the warranty. However, some companies will claim you broke the card if they can tell you opened it up, even if you didn't damage it. I would assume that if you open your card, you will have trouble getting it repaired under warranty later on.
Man! 've been trying to get my Omen 30L 3090 cooled for the past few days, and it has been an absolute hassle. My GPU is at 46°, but VRAM is 102°. I sure wish I would have seen your videos before I ordered those same thermal pads (blue package you ordered) in 1.5mm, because they definitely are a tad thick and they're not cheap. Replacing the pads for the backplate did nothing for my temps, so I'm currently trying to figure out a solution to directly cool the backplate. I did find it quite odd that there was thermal compound for the VRAM to the bracket yet nothing to bridge the heat from the bracket to the heatsink. Maybe some thermal compound would bring those temps down a few degrees on that side of the VRAM.
I just finished opening up my 3090 and replaced the 1.5mm pads with 1mm ones. That helped make it easier for the GPU to make contact with the heat sink. I also used a thin layer of thermal paste on the middle bracket where it makes contact with the copper to help transfer the heat. I also used liquid metal thermal compound on the GPU die and saw a little bit lower core temps, but this kind of compound is conductive and very risky. I would probably stick with the regular paste. Since you already changed the pads, I think the paste on the middle bracket may be important for the VRAM to cool properly.
Update: I added thermal paste around the bracket where it connects to the heatsink. My VRAM has dropped from 102°-104° down to a stable 90°. I can't put into words how happy I am right now!😆😆😆
@@RandomGreenFishPhone yea I also learned it's a feature on the "QuickMiner", I use just the regular NiceHash programs... so it doesn't show as much info
Yes, but it was hard to close everything properly and I had to squish the pads a bit. You may want to use thinner pads for the vram chips on the front side where the heatsink mounts.
@@RandomGreenFishPhone thanks a lot for the video and the info! subscribed :) one quick question: did you use 1mm pads on both sides of the 3090? i seem to remember reading on reddit that it should be 1mm on one side and 1,5mm on the other
@@unexampled I have 1.5mm on both sides right now, but I would use 1mm on the side where the heatsink and fans connect, because it was hard to put everything together with the 1.5mm.
@@RandomGreenFishPhone great, thank you again for the info! it's priceless lol, can't really find it anywhere else. i've been playing with the idea of watercooling the gpu, given the temperatures and the fan noise levels... is that a really dumb idea? 😅 (not considering the prices, which are pretty insane)
It will help having lower ambient temps, but only a little bit. Plus the extra cost for the AC is not desirable. Ideally, I would like to keep the room at 76F this summer and still be able to keep the card cool.
Thanks for the videos. Is there any way you could measure the dimensions of the 3090? I just got an Omen with 3090 that I was thinking about swapping video cards with my current case but wanted to make sure it fit. Thanks!
I really wanted to try out the 3090 but I couldn't find it by itself without paying a huge scalper tax. I got the entire computer for just under $2800. Not great, but considering the market it was acceptable.
@@RandomGreenFishPhone That was sort of my theory.. I bought one of these last night and canceled the order this morning.

Did you remove the top plastic layer from the backplate to attach that additional heatsink and fan? Does the plastic layer come off easily and can it be attached back afterwards?
I didn't remove anything from the backplate and didn't notice a plastic layer, besides the RTX label. I just used some thermal pads to stick the heatsinks directly on top of the backplate.
How much difference do the heatsinks make vs just a fan on the backplate? Also how thick are the thermal pads attaching said heatsinks?
I removed the fan and heatsink to test their impact on the VRAM temps. Ambient temp is 75F and mining at 120MH/s at 305W, without the fan / heatsink the VRAM temps are at 96C. With only the fan the temps dropped to 92C. With both the fan and heatsink, the temps dropped to 88C.
Nice video! I have the omen 3080 having the same issue. If I don’t change the thermal pads, will the heat sink and fans be enough to help? Can I have the details to the fan and heat sink you used? I am assuming it’s radiator fan you use blowing upwards?
It may help a bit, but without changing out the thermal pads inside I wouldn't expect too much. If you try it be sure to let us know the results :)
Heat sinks in the back wount do much, as without thermal pads there is no contact and proper heat transfer to the backplate from the board.
@@RandomGreenFishPhone Hello there
I have a model which is 3080. My Afterburner settings are as follows.
-power limit 65%
-clock -100
-Mem +1000
-Fan 90%
I got 91 mh rate. Junction heat is 106 celcius. When I set up the power limit 70 junction heat increase 108-110. I guess it's the most logical option to keep the power limit at 65.
106 junction good value for mining? Do I really need to change the pads?
@@RageofTurk The tjmax for ddr6x memory is listed as "+95C" on micron's website: www.micron.com/products/ultra-bandwidth-solutions/gddr6x
You may also find this article interesting: www.hardwaretimes.com/mining-ethereum-raises-gddr6x-temps-to-110c-in-3080-and-3090/
"The takeaway from this is that mining for longer durations, 24/7 as is usually done, with the memories running at 100-110C, seems like a recipe for a premature card failure."
Hey bro.
How do you turn on the light on the CPU cooler? I have the same PC but mine isnt lit up..
Stupid question: where did you plug in that fan on top of the 3090 heatsink?
I had to use a splitter. I plugged that into the fan header where the front panel fan is connected, by the USB 3 connection.
@@RandomGreenFishPhone Why a 1-3 splitter? Can't I just use a 1-2 to add a fan on top of the GPU heatsinks?
@@sneekeeboi I have another fan at the bottom of the case by the power supply to try and improve the air flow. If you only want to add 1 more fan then a 2 way splitter is fine.
I did this with the 3080 in my Omen PC. I used Gelid thermal pads (as they where available). The 2mm was way to thick, so I used 1mm. I also replaced the GPU thermal paste and added paste to copper contact area's. This gave amazing results for my VRAM. My core temps are now about 8-10 degrees higher, which is weird. I reapplied the pase (a bit thinner), which made no difference. Then I added a 1mm pad on the back of the GPU core, this still did not make a difference. I wonder if I need to add a thicker pad between the GPU and the backplate.
Did you figure this out?
@@THEMANZ6 I opened it up once more to take a look. Closed everything up (a bit tighter this time) and tested again. Still some weird core temps. Shut the system off and let it sit overnight. The next day everything was great, and has been up to this day. I can't really explain what happened. Maybe the pads expanded the smallest of amounts and made better contact.
Better results than I got 😆 still can't figure out why I'm getting a bios error for the card after redoing the pads and paste, though I did use the 1.5 mm thermal right pads and it does seem like the 1mm would be a better fit for how much compression there was. Used mx-4 paste as well. 🤷♂️ I've taken it apart a handful of times now and tried to figure out if I did something wrong but everything looks good - Even so I appreciate the content and the learning experience.
The first time I put the card together with the 1.5mm pads I didn't have everything tight enough to fully squish the pads so the processor and the copper plate weren't making full contact, resulting in extremely high core temps. Maybe the same thing is happening with your card and the temps are so high the bios is shutting things down.
@@RandomGreenFishPhone I thought that at first but it's a post error, no blank screen or anything, just immediately beeps at me 5 seconds or so after boot. I have one more theory to try and after that I guess it's rma.
@@alexheath7856 Weird... The only time I heard my computer beep during boot was when I forgot to plug in the power to the graphics card. Sorry I can't be more help, but please let us know what you do when you fix it.
@@RandomGreenFishPhone will do, I did not see an LED light anywhere external or internal but 3 low tone beeps and 3 high tone translated to the LED code is not detecting graphics card - took a minute to piece that together on HPs site. If I get it figured out I will post again incase others have the same issue.
@@RandomGreenFishPhone It happens to me as well. The 1.5mm on the front of the Hp rtx 3090 card will elevate the cooper plate so more heat resistent from the die to the plate. It results in temp rise instantly to 100C when underload. Changed to 1mm and it immediately fixed the problem. After playing with it for a week, the black metal frame in the hp rtx card is mainly what causes this sensitivity problem to the thermal pads. You want that metal frame to be as close as possible to the GPU circuitboard so 1mm or even less than that would be better. I tried modding all situation, from having all the thermal pads on all parts of the circuit board, to the VRAM only, and it DOES NOT improve the temp significantly. Should keep in mind that the thermal pad is to fill the gap so the two surfaces make contact for heat transfer, it actually resists the heat if adding the thickness. I have seen a lot of people using the thermal pads as a holy grail to having more heat transfer. As an engineer, I can say that it is not. But in fact, you want the thermal pads to be as thin as possible and just enough to make contact with the two surfaces. Good luck.
interesting that this happens on a 3080 as well as 3090, and not a HP model as well, at least that rules out any kind of manufacturing defect unique to the custom HP 3090
why no mining program starts on my omen 30l 3080rtx i9 can you help me please ?
Nice vid bro , just wondering your thoughts about hp's 3080 you think it would have the same sizes oncthe thermal pads?
Sorry, I haven't come across a 3080 used in the HP Omen. It appears that manufacturers are using anywhere between 0.5 - 3mm depending on the fan and heatsink design. You may want to open yours up and measure the thickness of the existing pads first, or buy various sizes if you want to avoid opening it up more than once.
@@RandomGreenFishPhone it will voids the warranty?
@@starkillertoy Simply opening up the card should not void the warranty. However, some companies will claim you broke the card if they can tell you opened it up, even if you didn't damage it. I would assume that if you open your card, you will have trouble getting it repaired under warranty later on.
Are the heatsinks attached somehow or are they just resting atop the backplate?
The heatsinks on top are held in place a bit by thermal pads, but not secured by anything else.
@@RandomGreenFishPhone I've gone from 110 degrees thermal throttling to 77.6 degrees maximum temperature. Thank you so much!
Man! 've been trying to get my Omen 30L 3090 cooled for the past few days, and it has been an absolute hassle. My GPU is at 46°, but VRAM is 102°. I sure wish I would have seen your videos before I ordered those same thermal pads (blue package you ordered) in 1.5mm, because they definitely are a tad thick and they're not cheap. Replacing the pads for the backplate did nothing for my temps, so I'm currently trying to figure out a solution to directly cool the backplate.
I did find it quite odd that there was thermal compound for the VRAM to the bracket yet nothing to bridge the heat from the bracket to the heatsink. Maybe some thermal compound would bring those temps down a few degrees on that side of the VRAM.
I just finished opening up my 3090 and replaced the 1.5mm pads with 1mm ones. That helped make it easier for the GPU to make contact with the heat sink. I also used a thin layer of thermal paste on the middle bracket where it makes contact with the copper to help transfer the heat. I also used liquid metal thermal compound on the GPU die and saw a little bit lower core temps, but this kind of compound is conductive and very risky. I would probably stick with the regular paste. Since you already changed the pads, I think the paste on the middle bracket may be important for the VRAM to cool properly.
Update: I added thermal paste around the bracket where it connects to the heatsink. My VRAM has dropped from 102°-104° down to a stable 90°. I can't put into words how happy I am right now!😆😆😆
@@schooty25 Glad it worked out for you 🙂
how many packages of thermal pads are needed for this?
2 packages should be enough for inside of the 3090 and you should be ok using a cheap thermal tape to hold heatsink in place.
how did you get Nicehash to display VRAM temp?
It just does if the card / bios supports it I guess. It doesn't show up with my 1070 and may not work for 3070s.
@@RandomGreenFishPhone yea I also learned it's a feature on the "QuickMiner", I use just the regular NiceHash programs... so it doesn't show as much info
Are you currently using the 1.5mm thick pads in the hp 3090?
Yes, but it was hard to close everything properly and I had to squish the pads a bit. You may want to use thinner pads for the vram chips on the front side where the heatsink mounts.
@@RandomGreenFishPhone thx!
@@RandomGreenFishPhone thanks a lot for the video and the info! subscribed :)
one quick question: did you use 1mm pads on both sides of the 3090? i seem to remember reading on reddit that it should be 1mm on one side and 1,5mm on the other
@@unexampled I have 1.5mm on both sides right now, but I would use 1mm on the side where the heatsink and fans connect, because it was hard to put everything together with the 1.5mm.
@@RandomGreenFishPhone great, thank you again for the info! it's priceless lol, can't really find it anywhere else.
i've been playing with the idea of watercooling the gpu, given the temperatures and the fan noise levels... is that a really dumb idea? 😅 (not considering the prices, which are pretty insane)
How can you see vram temps on nice hash
What if u use the regular omen pc but your room has AC? Will it keep the omen cool??
It will help having lower ambient temps, but only a little bit. Plus the extra cost for the AC is not desirable. Ideally, I would like to keep the room at 76F this summer and still be able to keep the card cool.
@@RandomGreenFishPhone thanks
Thanks for the videos. Is there any way you could measure the dimensions of the 3090? I just got an Omen with 3090 that I was thinking about swapping video cards with my current case but wanted to make sure it fit. Thanks!
You're so smart, why did you buy this prebuild?
I really wanted to try out the 3090 but I couldn't find it by itself without paying a huge scalper tax. I got the entire computer for just under $2800. Not great, but considering the market it was acceptable.
@@RandomGreenFishPhone That was sort of my theory.. I bought one of these last night and canceled the order this morning. The sales rep assured me that these were fitted the founders version of the RTX 3090.. Then I saw your video and realized this was not a founders card and was pretty pissed.. then trying to cancel an HP order is a nightmare. I was put on hold for 45 minutes! Gave up, went to the chat and waited forever there to finally be asked a ton of "Are you sure you want to cancel?" questions... Ugh.... can't do prebuild.
@@timotmon I was actually more impressed with the Skytech vs the OMEN. Better build quality, packing, thermal performance, and no bloatware. But I absolutely prefer to build my own PC when the parts are available.
@@RandomGreenFishPhone Just checked them out.. yeah that would be the way to go, but no 3090 it seams. Frustrating... I'm not a gamer or a miner.. I use these cards for rendering my work. I suppose the write off is a perk.. but 3K for a video card.. FFS.. Great vid though.. glad you posted these!

You should crank up the memory overclock and see what it can do. You should be able to get 100MH/s out of a 3080 and keep it nice and cool. I am curious how well a waterblock compares.
