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!
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
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 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 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 I’d probably take an an otherwise garbage oem 93mm fan and zip tie it to the back. I’ve done this before, zip tying an Amd stock fan to my pcie brackets. Doesn’t really do anything but it’s the thought. Also the last modern cards to come with blower coolers were 20 series
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.
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. :))
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...
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.
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.
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.
You're much better off getting a case with fan mounts on the bottom so you're pulling fresh cool air directly into your GPU fans. But I suppose this is a practical hack if your case doesn't have any and your GPU is running excessively hot.
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.
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.
That would be better as an intake seeing as it’s below your gpu fans which are intaking. You’re pulling the hot air from the gpu towards where the gpu fans are pulling air into the gpu. Not the greatest setup but more airflow is still more airflow.
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).
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.
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
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
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.)
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.
Hello nice vid ! I just go a lianli lancool 216 and this is and option on this pc case so i was thinking about trying but it seems not worth it - Ty, new sub.
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.
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...
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.
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.
@@DLMtechgarage and yet, there are still idiots out there who think it is about the number of fans in their case, even though having more beyond where you should (back a couple in front) does not lower temps by more than 3 C....SMH
Hah! I've done this before as an experiment and ya, it does work. It's just too ugly- I had the fan on the inside though. It was just a standard size fan (I think 80mm)
Over the slot covers/grills...? WhatTF are you thinking!??? Remove them already!! That will give way more airflow and way less noise... you do realise that right..?! not too difficult for you to grock? And no it wont help on a blower style cooler: The warm air exhausted by you GF card ends up right back in the intake area, where it's recycled in a ever hotter loop. The fan minimises that... If you want a cooler, quieter blower style GF card; remove its grille already! Hellooo!!!
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.
