R.I.P SLI!. When using 2 graphics cards like a decade ago, this used to make significant difference in temps for my top GPU back in the day. I even had a second fan wedged at the start of the 2 GPUs and had a wind tunnel effect going on. Game changer in Summer!
A mate of mine used to work as a sheet metal fabricator, and back in the day he had a passively cooled NVidia card (something like a 8800GT) in his home PC. Because it's chunky heat exchanger was inside a hot case with multiple mechanical hard drives, an overclocked CPU, and a PSU all spewing out heat it ran concerningly warm, and during that summer the GPU started to over heat and glitch out, so he decided to build a replacement alloy side panel for his case that incorporated a large curved duct and had a pair of 120mm fans blowing room temperature air straight through this GPU's massive heatsink. I can't remember the exact numbers but it worked ridiculously well, dropping the temperature from (IIRC) around 85'C (185'F) to something like 65'C (149'F). This ducted cold air setup allowed him to run it stably with a surprisingly aggressive overclock. Unfortunately, time (And technology) moves on, and in less than 12 months he'd upgraded to another new graphics card and the ducted side panel no longer fitted properly.
Thing that is also important is that you want more fans blowing ‘in’ the machine than ‘out’. Or that you have a positive presure inside instead of negative. Why? You have these holes in the back of the case without a filter. If you have a negative presure dust Will be sucked in. Of there is a positive presure, it wil allways blow a bit there. I have a positive presure in my case, and after a year there is almost ‘no dust at all.
Agreed. With my older case which also had a couple dust filters here and there, there was always a layer of dust after like a year. With my newer case where I designed the airflow much better, there's next to no dust and I haven't cleaned it in atleast like 2-3 years if ever. I don't remember ever seeing dust in there.
I did this exact thing to keep my cheap, undervolted Titan X cool/quiet enough while holding over for GPU prices to drop :D I used one of the included case fans with my Seasonic Syncro Q704 (120mm Nidec fans) and it fit perfectly on the case I was using (Phanteks Evolv X). I used zip ties to give it a nice, secure mount. I also removed the PCI brackets and mounted it INSIDE the PC btw.
I mounted an old Intel CPU fan with some tightened wires on the back of my case a few years back, never thought about it until I saw your video, but it works life a charm.
there's an effect where air moving gets the air around it moving, Bernoulli's principle I believe. by having open mesh around a fan, you allow the air outside of what the fan moves to move together generating more airflow than if the fan was fully sealed off. Each application will create different effects, but my testing with sealing up holes on the rear with your exact reasoning found that blocking the extra pathways cooled worse. rear fan as exhaust like this seemed less efficient compared to rear fan as intake, if your pc lives in a dusty environment an air filter is suggested for running a GPU rear intake.
I did this with my old build. at first I took the rgb fan off the original ryzen heatsink and mounted it in that exact area. worked like a charm on my first pc and ive been doing it ever since. 80mm fans seem to fit the best. not the best for dust tho but oh well. lol
There's a PCIe Fan Mount from Silverstone that does exactly this. There are also Metal Fan Spaccers with magnets at the corners, so you could just slap a fan behind it. But in the end vertical GPUs and rear exhaust GPUs like Nvidia Founders Edition and Acer BiFrost should benefit the most of it. Maybe also passive PSUs.
I taped one fan under my GPU and had it setup where it would blow air to the GPU. And open up the side panel. The temps on my 580 went from 73 to 65-66 after 1 hour of gaming. The thing was amazing!
I put a 90mm fan from an old shitty PSU (silver office psu) and it drops 5 degrees, this is amazing. I wonder if buying something like noctua 93mm fan would further drop the temps. Anyways, nice find and thanks for sharing.
well uh i have a RX 570 with no back plate but i used a broken old GTX 760, 3 fan and one the the fans didnt work so i cutted the plastic off the left side where the fan broke, and placed it ontop of the RX 570, 2 fan (now a 4 fan) No back plate but holy i dont have VRAM temp senser but the GPU was down by 5c. BTW the fan connectors was the same as the RX 570 connectors, used a splitter and it was cool
i do use a 80mm fan below the GPU but installed by inside, had to remove those metal things you take off where you plug the monitor cables, i dont see a big difference but makes me feel better
I feel like this was just caused by hot air not exhausting good enough in stock config. Esp since you said PCI fans didn't work, it was probably just recirculating hot air coming off the side. You should try using the delta fan as the case exhaust and see if it gives the same difference
But what was the temperature delta vs ambient? Pulling directly in is better. It raises inner case tamps but lowers core temps which is where performance lies.
SIDE FAN rocks if you have a case that supports this... my crappy older case has way better cooling than most modern cases. My side fan is right next to my graphics card and the air coming out is pretty hot even though it's only running at 300RPM and can't even be heard. In fact, I feel hot air even when the fan isn't installed. I modded my GTX1080 with Noctua fans and have a pretty much dead silent PC using "FANCONTROL" software. I can only just BARELY hear my computer and that's ONLY if a game is stressing my GPU. It's 100% dead silent for most tasks as my Noctua fans sit between 300RPM and 500RPM most of the time.
I see that there are already holes in the PCI brackets... You just need one screw to attach it firmly, and if you're lucky, at least 2 holes will match with the holes in the fan. And probably you can fit it inside the case...
Your fan was configured to exhaust hot air, but I believe the opposite might be more beneficial. Configuring it to intake air would supply fresh air directly to the GPU's fans. You could also switch the bottom front fan to function as an exhaust to improve airflow. I watched two videos from Major Hardware and Optimum regarding channeling air to components with ducted air supply, and it significantly improved performance by approximately 10 degrees.
I guess not because - as far as I know - the graphics card coolers are designed to intake the air inside the case and exhaust to the rear. For that you would need to mount the fan lower, otherwise the graphics card fans have to fight against the rear cooler.
@@Durayne the holes in the PCIE slot are so insignificant that the gpu fans wouldnt really care. Forcing air through small unsealed holes with a fan at distance is difficult.
@@pineapplej7310Of Course you cant apply static pressure in that scenario. Still youd probably have colliding air streams. I supply my graphics card with fresh air from the bottom, as I use the torrent compact with some bottom fans.
i feel like it does create negitive pressure i mean (2 intake 4 exhaust isnt good) but doesnt it suck in dust and suck in hot air from the PSU and top exhaust fan? i aint no expert but still
I have done an identical solution in 2009 but somewhat more professional with a 92 mm fan and a metal bracket mounted on the back as I operated an HD 5870 and an 8800 Ultra in the same machine using hacked drivers to get PhysX from the 8800 Ultra and graphics from the HD 5870. Both were stock blower cards and it made a huge difference.
I built a fan stand out of some K'nex and angled it under my 3080ti, overall minimal improvements, but anything to bring those memory temps down is a win Same Corsair case here as well
I did this but I put the fan (80mm Arctic) inside the case as a intake, fans are running at 40% instead of 50% in benchmark with the same temps, so in my case it was a improvement, it's quieter now. :))
Warm air rises, would it make a bigger difference turning the fan around so it blows cool air in under your video card, the video card fans blow the air up and the psu blows the air out. (Dust could be a problem depending on your environment.)
Kind of looks like you don't have fans on the front grill. Fill the front with as many fans as you can mount inside the front case, and put a fan with high CFM on top and rear exhaust. That will be take care of all the trapped heat in the case.
Ahhh well, adding more airflow reduce Temps a bit. Here is a hack Put an AiO on the CPU and GPU, and put the radiator outside the case. Preferably the side you never see. Or if you have an awesome looking radiator it's fine too. Aquacomputer makes some that look great. Adding some fans that lock modular without cables. On the other hand. I had a really neat bench case with very clean cables n tubes. Actually mounted on the wall, too.
Based on youtube videos where people test pc case airflow using a smoke machine, the gpu sucks cool air from outside the case from the pci slot holes. Sounds weird but I guess that's how pc case engineers does things. The best gpu temperature improvement you could get is blowing air into the case rather than exhausting it. I don't have any test to prove this but it kinda sounds about right.
I just tried it and it didn't made any difference at all actually, my casing was perfect for to fit a fan near pci slots, But still it didn't made any difference when at full load. But now gpu cools down much faster than before when unloaded the load.
Edit: ~whoa, now that I’ve watched the video to the end, why are you exhausting air? It would only make sense to suck air out if it was a blower card. A dual/triple fan cooler, you should be blowing air in. Try that.~ Getting cool air directly to your GPU that takes hot air from inside your case and releases hotter air inside your case, placement is good, but back in the day, we didn’t use stupid crap like glass for side panels, so you could mount a fan on the side panel and achieve the same thing. To be fair both of my currently in use cases have glass side covers, but I’m liquid cooling. You can do it a lot cheaper than you’d think, maybe $200 is a lot for most people, never mind.
at this point, if I could buy a pc like this, I would probably think about a deshroud mod kit for the 3090. there are a lot on the internet, ready to mount and the temps improvement is about 15/20 C° less, under heavy load
Best cooling solution is to remove side panel, nothing comes close to it and you won't need exhaust fans anymore, the only downside is dust but having dustblower and hoover will keep your pc clean as day 1 if done once a week.
If he had serious case flow issues it might have worked. All things are relevant. You could just have stronger cross flow in your case by having better or more fans in the front of the case. I can run my 4080 super overclocked all day on testing and no noise. 3 140 mm front inlet 3 360 back inlet fans a 420 aoi exhaust out top and one 140 exhaust in back. I had to find an optimized mix of the them but it works amazing considering I also have an overclocked 14900k hence the 420 aio
Did this same test as well and also printed 3d bracket to move air flow inside the case and feed rear GPU fan with air - either additional exhaust and intake didn't made a difference. Maybe because i was running additional fan at reasonable speed to not make more noise than GPU itself does. For me, there is no point of adding fan if I can't lower temps without increasing noise. If only temp is the problem - I have few 5-6k rpms delta fans from servers as well as 3 120mm 6k RPM server rack fans - I can put them on and crank the speed to the max. Temps will be lower, but at what noise costs? Also I think it depends on GPU and case airflow. I have 3 front fans blowing nicely air and I think they have enough power to blow air through the case, without need for additional GPU exhaust fan.
Best thin you can do is give it colder air. If you would put small fan coil climatisation in a box with your pc, to reduce amount of air and seperate this air from your room. This can keep air at for example 15c, keeping your air that enters pc really cold, is like playing games at winter when it is summer.
I think it is supposed to be a smaller fan just under the gpu as an intake so more fresh air come in for the gpu, shouldn't interfere with the pc airflow cuz they tend to rise up and that fan is at the bottom
You have to put the fan in the opposite direction. Then at the top of the case you should install two powerful fans from inside to outside. Then I think there will be a massive difference.
As a non engineer I think your whole fan setup should be reversed as the small cold air intake to push the air over the gpu and out the triple wide front panel would bet better for gpu temps and a cost of cpu temps ( which tend to be more stable), in theory a non vanity case could also use a metal side with a mesh cut for an intake fan of a much larger diameter to not require such a high rpm/level of sound and no look as tacky. Also who spends the time to tint glass for a pc case, that is literally burning money for no value like buying a rolly when far better high end watches exist at half that price... And that pc with those peripherals... that setup looks like my drunk homeboy robbed a rich kid of their prebuilt buy only had time to take the tower...
I agree that this isn't worth it. I've experimented with mounting fans in all sorts of places to better cool my gpu but I found that the gains were minimal. Also should warn anyone that using a fan with too high rpm blowing towards the card could actually damage your card or card fan. This is a problem for cpus too. Basically you can end up spinning your gpu or cpu fan too fast, causing it to become a generator. That's why when you get a dual fan set up like noctua cpu coolers, the fans are identical and spin the same speed to avoid this problem. Best option IMO is just adjusting the fan curve in MSI afterburner. I cooled an rx 560 from 83C to 70C, but most games it runs at about 66C. So a difference of 13 degrees, which was a lot more than any extra fan configuration. Most gpu fan curves are set up from factory to balance between cooling and quietness. Aside from a custom fan curve, setting up an underclock helps keep it cool too. Both these options can work in tandem to cool better than extra fans, and not potentially turn your actual gpu fan into a generator. Lmao.
Had that fan been attached as a fresh air intake directly below the GPU you probably would have seen a significantly lower temperature than what you got. Of course, put the big Delta fan in the case as a lower-front intake, you'd likely see a big change in temperature there, too. Or just discard the side panel. Best yet, just leave things alone. 72C isn't bad. And the extra fan is a lot of BS for very little (and unnecessary) temperature change.
lol I got a small desk fan that I currently have facing into my pc case. It lowers my CPU temps by around 5°c when not under load. It's also very loud (although I don't mind too much).
Instead of tinkering with toy fans, plug an electric leaf blower directly to the intake of the PC case. If its too noisy, leave it in the garden and run a tube to the PC. That will cool your RTX 4090 and the i9-14900k CPU.
so just scored myself a used RADEON HD 6450 1GB GDDR3 for my 530S internet browsing and youtube....for pennies on ebay....but the card does not come wit a fan on it.....touched the heat sink - was really hot could barely hold my finger on it....but put a small 5 volt .200 amp fan on it via usb made all the difference ...now it's cool to the touch. 530S not really designed for card like that :) so getting a usb fan probably costs as much as the card itself nowadays....but it works. now need to figure how to fit the fan on card....now it kind of just sits there #lolz
@@DLMtechgarage great idea....was thinking hot glue gun but not sure would bite to metal + metal getting too hot....but if metal stays cool might work..I like your idea though...
Actually janky since the cold air from the GPU (which is minimal already in most cases) is taken away from it. There should be better results with the fan blowing inside the GPU / creating FAN ducts towards the GPU aswell as isolate the GPU fans from the backplate where the air will be circulating back to the fans.
Help me please I want this assembly i7 4790 128 GB SSD 1 to the hard disk 10 GB RAM with motherboard and PSU Mini Boîtier Simple How much does it cost please
Im guessing 130-220 dollars depending on ur motherboard. If you are gonna get it through a dell optiplex build its gonna be on the chrapeiside. Also i dont think 10gb ram is possible since there aren't 5 gb ram sticks, unless you are mixing ram ofcourse WHICH YOU SHOULD NEVER DO. Settle for 8gb ram instead
@@JonLeonard wouldn't matter if he was mixing ram or not, there is no 10 gigs of ram unless he's got 10 ram slots at 1 gig per stick... which the actual number would be 10.240 gigs.

R.I.P SLI!. When using 2 graphics cards like a decade ago, this used to make significant difference in temps for my top GPU back in the day. I even had a second fan wedged at the start of the 2 GPUs and had a wind tunnel effect going on. Game changer in Summer!
It's too bad Nvidia and AMD could never get SLI to scale properly. I had so much fun building dual and triple GPU water cooled rigs.
ya i had gtx480 SLi and fumbled with spare parts, did exactly the same thing, temps dropped about 8 degree
A mate of mine used to work as a sheet metal fabricator, and back in the day he had a passively cooled NVidia card (something like a 8800GT) in his home PC. Because it's chunky heat exchanger was inside a hot case with multiple mechanical hard drives, an overclocked CPU, and a PSU all spewing out heat it ran concerningly warm, and during that summer the GPU started to over heat and glitch out, so he decided to build a replacement alloy side panel for his case that incorporated a large curved duct and had a pair of 120mm fans blowing room temperature air straight through this GPU's massive heatsink.

Unfortunately, time (And technology) moves on, and in less than 12 months he'd upgraded to another new graphics card and the ducted side panel no longer fitted properly.
The Lian Li Lancool 216 case already has this feature, it comes with a backplate bracket for the 120mm fan that exhaust air from the case.
My first real case and i like the 216. I have a small computer room and my case is lying down so how would one set up the fans?

did it lower your gpu temp significantly?
When I switched over to a hyper 212 from the stock AMD cooler, I noticed an slight increase in GPU temps. Any air movement will definitely help.
yup, even hot air is better then no air!!
Maybe we’ll live in a future with 3 front intake and 3 rear exhaust fans for cases 😅
lol!!
I mounted an old Intel CPU fan with some tightened wires on the back of my case a few years back, never thought about it until I saw your video, but it works life a charm.

can you mod a case so putting a fan in the back fits better
it would be tricky!!
Tbf their are those solid front panel cases that are terrible. So I could believe around 8-9c.
They also kinda boost higher with lower temps untill they reach that point

I can run my 4080 super overclocked all day on testing and no noise. 3 140 mm front inlet 3 360 back inlet fans a 420 aoi exhaust out top and one 140 exhaust in back. I had to find an optimized mix of the them but it works amazing considering I also have an overclocked 14900k hence the 420 aio
i see this would be most beneficial if you're running more than 1 gpu inside your case with lots of hot air trapped inside the case
Did this same test as well and also printed 3d bracket to move air flow inside the case and feed rear GPU fan with air - either additional exhaust and intake didn't made a difference.
Maybe because i was running additional fan at reasonable speed to not make more noise than GPU itself does. For me, there is no point of adding fan if I can't lower temps without increasing noise.
If only temp is the problem - I have few 5-6k rpms delta fans from servers as well as 3 120mm 6k RPM server rack fans - I can put them on and crank the speed to the max. Temps will be lower, but at what noise costs?
Also I think it depends on GPU and case airflow. I have 3 front fans blowing nicely air and I think they have enough power to blow air through the case, without need for additional GPU exhaust fan.
A case with more airflow will be a better investment after looking at the power use from your pc wear and tear on PSU
Best thin you can do is give it colder air. If you would put small fan coil climatisation in a box with your pc, to reduce amount of air and seperate this air from your room. This can keep air at for example 15c, keeping your air that enters pc really cold, is like playing games at winter when it is summer.
So how would I go about this? Do I put my PC in a cardboard box with my fan?
@@zoro-i8u a box would be better than all cases that have glass panels.
I think it is supposed to be a smaller fan just under the gpu as an intake so more fresh air come in for the gpu, shouldn't interfere with the pc airflow cuz they tend to rise up and that fan is at the bottom
What about having the fan mounted on the backplate of the gpu, somehow?
You can open the entire case and use a giant fan for the entire pc
::presses down duct tape:: that's professional right there!
or just buy a case that you can mount fans under the gpu. have 2 under my gpu and havent seen temps over 60
You have to put the fan in the opposite direction. Then at the top of the case you should install two powerful fans from inside to outside. Then I think there will be a massive difference.
you can always lower the temps if you're willing to stand the noise
They sell magnetic ones to stick em on back for like 2$ aliexpress
As a non engineer I think your whole fan setup should be reversed as the small cold air intake to push the air over the gpu and out the triple wide front panel would bet better for gpu temps and a cost of cpu temps ( which tend to be more stable), in theory a non vanity case could also use a metal side with a mesh cut for an intake fan of a much larger diameter to not require such a high rpm/level of sound and no look as tacky.
Also who spends the time to tint glass for a pc case, that is literally burning money for no value like buying a rolly when far better high end watches exist at half that price...
And that pc with those peripherals... that setup looks like my drunk homeboy robbed a rich kid of their prebuilt buy only had time to take the tower...
I agree that this isn't worth it. I've experimented with mounting fans in all sorts of places to better cool my gpu but I found that the gains were minimal.
Also should warn anyone that using a fan with too high rpm blowing towards the card could actually damage your card or card fan. This is a problem for cpus too. Basically you can end up spinning your gpu or cpu fan too fast, causing it to become a generator. That's why when you get a dual fan set up like noctua cpu coolers, the fans are identical and spin the same speed to avoid this problem.
Best option IMO is just adjusting the fan curve in MSI afterburner. I cooled an rx 560 from 83C to 70C, but most games it runs at about 66C. So a difference of 13 degrees, which was a lot more than any extra fan configuration. Most gpu fan curves are set up from factory to balance between cooling and quietness.
Aside from a custom fan curve, setting up an underclock helps keep it cool too. Both these options can work in tandem to cool better than extra fans, and not potentially turn your actual gpu fan into a generator. Lmao.
gpu fan speed?
system temp?
cpu temp?
I have a fan there but on the inside, I flipped it so it blows cold air in under the gpu fans.
Has a small difference
Had that fan been attached as a fresh air intake directly below the GPU you probably would have seen a significantly lower temperature than what you got.
Of course, put the big Delta fan in the case as a lower-front intake, you'd likely see a big change in temperature there, too. Or just discard the side panel.
Best yet, just leave things alone. 72C isn't bad. And the extra fan is a lot of BS for very little (and unnecessary) temperature change.
ig its one of those things you can try if you have a spare pc fan and don't kno what to do with it
Have you tried a 200+ CFM beastly fans? GFB1212VHW for example. (also doubles as carrot slicer so mind your fingers!)
Maybe only cooling the sensors and not the components ?
Try blowing in fresh air like falcon does it.
My GPU runs @ 63 ~ 65 and gpu memory: 65 ~ 70 underload. Zortac 4080 super.
you installed it wrong if you put airflow side to your gpu its makes your card dirty but air make your card cool as hell
I think it would have made a bigger difference if you took the PCIe Case Shields out of your case.
i do this , but the cooler fan not outside but inside, and so cool upto 5-8C i got improve
lol I got a small desk fan that I currently have facing into my pc case. It lowers my CPU temps by around 5°c when not under load. It's also very loud (although I don't mind too much).
loud or heat pick one
Get a case with a lot of ventilation to avoid drastic measures.😆
very true lol...
Instead of tinkering with toy fans, plug an electric leaf blower directly to the intake of the PC case. If its too noisy, leave it in the garden and run a tube to the PC. That will cool your RTX 4090 and the i9-14900k CPU.
3:13 Fixing a fan to the case with adhesive tape is the same thing as asking to dislike the video...
he couldve made it permanate you never know
Thanks to your video I started to use mod like this too 😊, it helps a little bit so anyway it is better than nothing.
so just scored myself a used RADEON HD 6450 1GB GDDR3 for my 530S internet browsing and youtube....for pennies on ebay....but the card does not come wit a fan on it.....touched the heat sink - was really hot could barely hold my finger on it....but put a small 5 volt .200 amp fan on it via usb made all the difference ...now it's cool to the touch. 530S not really designed for card like that :) so getting a usb fan probably costs as much as the card itself nowadays....but it works. now need to figure how to fit the fan on card....now it kind of just sits there #lolz
Use some type of sheet rock screws as it bites into the heatsink. I have a video showing that on the channel.
@@DLMtechgarage great idea....was thinking hot glue gun but not sure would bite to metal + metal getting too hot....but if metal stays cool might work..I like your idea though...
bro remove glas panel.i got 3080.and i get like 65 degres in like 2 haurs of gaming
I fitted a AIO on my gpu mine stays 120f to 130 best decision I made. The max temp before was 220f
You might get that same 5 degree drop by removing the Side Panel...
best cooling solution for gpu i still watercooling, my 4090 never reach 50°c
New Subscriber i love your voice ❤❤
Thanks for subbing!
take the glass side panel off your case, even better!
I tried both methods, temp dropped 1-2 degrees.
turn up your intake fans and have postive air flow....your welcome
Itd probably work better with blower style card, as you your self said
Actually janky since the cold air from the GPU (which is minimal already in most cases) is taken away from it. There should be better results with the fan blowing inside the GPU / creating FAN ducts towards the GPU aswell as isolate the GPU fans from the backplate where the air will be circulating back to the fans.
Help me please I want this assembly
i7 4790
128 GB SSD
1 to the hard disk
10 GB RAM
with motherboard and PSU Mini Boîtier Simple
How much does it cost please
Im guessing 130-220 dollars depending on ur motherboard. If you are gonna get it through a dell optiplex build its gonna be on the chrapeiside. Also i dont think 10gb ram is possible since there aren't 5 gb ram sticks, unless you are mixing ram ofcourse WHICH YOU SHOULD NEVER DO. Settle for 8gb ram instead
@@JonLeonard wouldn't matter if he was mixing ram or not, there is no 10 gigs of ram unless he's got 10 ram slots at 1 gig per stick... which the actual number would be 10.240 gigs.
Why 10gb ? Shoot for 16gb
Try 12GB, not 10GB of RAM. '1 to the HDD'?
Get a nvme and a ssd for blazing speeds
now you need to display the laptop version of this =)
i've put a tiny exhaust fan UNDER the gpu and it improved thermals by a lot
direct airflow work 100%, the lower i can get is 65 for gpu and 60 for cpu but with very good airflow after that it is a waste of power
I don't think your gpu is a blower style one, but if it were, you would see a much bigger improvement!
