I’m concerned since my 2080ti is idling at 58c. I have that intake right next to an exhaust and I’m not sure.

Ah! I was just about to update everyone. I repasted my 2080ti, and used 3 thermalite 92mm low profile fans. That brought the temps down to 66 under max graphics benchmark on Rainbow 6 siege!
Mission accomplished boys!

Yep! Now to uninstall rainbow 6 and get back to playing FTL at 60fps locked, windowed 720p. Lol
I also did the fan config like you suggested. I may even take the top exhaust fans off all together.
Thank you for the thorough response.
While I’ve been building computers since the original i3/5/7 series, I have always had full sized cases, or obscure goofy cooler master cube cases. This is my first tiny case that isnt something like a split ITX SFF case, and I have to actually thing about airflow. I had strong thoughts that the front top two corner fans were causing dead air pockets, my CPU cooler was ripping at higher RPM once the machine started going, and it almost seemed like the 2080 was exhausting right into the CPU cooler to eject out instead of being whisked out.
The GPU, I may have misrepresented myself once again. But this is my first time with an 80 series card, or any kind in its class. First thing I did when I got this card was thermal paste, I haven’t undervolted yet, and really until I figure out this airflow situation I believe overclocking is going to be met with thermal throttles before I get anywhere close to gains. Im hitting thermal throttle at 85c (for some reason NVIDIA experience arbitrarily set that?) Riva Turner shows relatively okay speeds, and load, but I cant get rid of that heat!
Your recommendations:
- This is a brand new PC (2080ti used) Ryzen 5700x, 32gb, 2080ti - No dust in sight…yet.
- Im thinking of 90mm fan swapping this 2080ti, the fans I have on this are loud under load. But the curve I have on it now I think is just dumping air into the chassis.
- I’m thermal throttling at 85c right now.
- “Bind the case fans to GPU” - okay so for this one, in my BIOS I don’t directly see PCIE, or GPU to bind fans to, but I can see CPU, VRMMOS, SYS_FAN, and SYSTEM1. I am assuming VRM_MOS is the motherboards not the PCIE’s? Gigabyte mobo.
(Already replaced thermal paste with arctic 5, that’s my go to. Also, a lot of fans now adays have resistors to prevent current from going back to the mobo if you get your fan going to fast.)
Previous builds, all with goofy, non standard cases: (Bunch of laptops, and USFF Dells) 8500/RX580 4770/1060 4690/R9 380 3770k/R9 290 970/GTX970

Oh it’s okay. I don’t mind asking dumb questions so it never helps. And I came on strong with my insecurities in the reply with needing to show I knew what I was doing lol.
Anyways, I’m on windows for now but planning on switching back to Mint once I get a good tune. So I’m gonna be in the same boat. I’m looking into low profile 92mm high static pressure fans.
Benchmarking is a good idea! I’ve been using rainbow 6 siege for testing constants. I took two pci brackets off the back of the motherboard and gave it some more flow but alas, I think I’m just hitting heat saturation. I have some spare fans I can test with tonight.
You need a 6th fan /s
Hmmm…yes. Maybe I could mount some 10mm raspberry pi fans in some spare gaps
IANA science person or wind expert, but I would test what effect removing/disabling the bottom intake has. Right now it could be pushing fresh air up and diverting it somewhat before it gets to the GPU intake (hard to say for sure based on just the 1 photo)
The trick with cooling is to ensure you have a smooth flow of air from one part of the case to the other, preferably opposite sides. Make sure your CPU coolers are blowing in the same direction as well.
It’s a little difficult to see from this image, but it looks like you have almost all your fans - intake and outlet - on one end of the case. This could create a big dead zone at the rear of your case. Especially for your GPU, sandwiched between CPU cooler and PSU. What I would do is move one or more of those fans to the rear, make sure front, rear, and CPU fans are all blowing in the same direction, and see if that helps any.
That thing on the GPU is a anti sag bar I printed it. Front and bottom are intake. Top and back are exhaust. Everything is supposed to be going front to back. I think the top corner fans are creating a dead zone.
I can rearrange my fans to see if that helps. It’s a small case so not many options for configuration.
I have 3 exhaust. (2 top 1 back) And 3 intake 1 bottom 2 front.
That’s kinda what I’m concerned about is the dead air
What’s the thing between the PSU and the GPU?
And what’s the orientation of the fans?The main question is: does your GPU have a no fan idle mode? AFAIK the fans won’t spin till the GPU reaches 60°C and cool it back down to 40 or 45, sorry can’t remember.
Usually you want to have a 3 intake at the front panel and 2 exhausts, one at the back inline with the CPU cooler and one at the top as far behind as possible. Since you’re running, what looks like, a mini tower you can with the same layout as a midi but 2+2 (2 intake front, 1 exhaust back, 1 exhaust top far behind). For a positive pressure you can mount an additional fan on top, at the front as an intake.
For the best result you should take your time and fiddle around, measure and document
That thing is a 3d printed anti sag brick lol.
The GPU fans spin around 55ish.
Oh! So if I flip the top front fan around it’ll work out better? Or should I just take that one off entirely?
I want all the fans filled if I could. But I’m okay even 3d printing air guides to move air along or prevent it from getting in specific places.
The anti sag brick looks nice but is restricting airflow from the side, if you can look for a stand for the corner of the GPU.
You don’t have to populate all available fan slots. I would recommend you to remove the bottom one entirely, even if your PC is on top of a table and dust isn’t a problem, this fan redirects a lot of the air, coming from the front 2, slightly up to the CPU.
The problem with the top one is, even if you rotate it to be an intake, it could push the air, coming from the front, down away from the CPU flow.
Short: try and simply remove the bottom and the top front one entirely.
Like someone already stated, you want the air to move linearly from one side to another.
I don’t recommend to use air guides since they can create pressure points and block other components. Components like RAM, VRMs and drives also need some fresh air.
Yea I guess you’re right about the anti sag brick. But it does have a bunch of speed holes in it I thought would be enough. I really don’t like the column antisag methods.
Ill disconnect the fans you all have recommended and report back.
Thanks this is my first small case like this. Usually I either have a big fuck all case or one of those mini ITX cases that you put the GPU on the back side of the mobo.
So how did it go? Were you able to bring down the temps?
Ah! I was just about to update everyone. I repasted my 2080ti, and used 3 thermalite 92mm low profile fans. That brought the temps down to 66 under max graphics benchmark on Rainbow 6 siege!
Mission accomplished boys!
85 thermal throttle on 2080ti
When did you last repaste your GPU? it is a good practice to clean and repaste your CPU/GPU regularly (once a year or so).
TBH I wouldn’t recommend this one blindly. Sure it would help but it depends on the skills, used paste and circumstances. Under “normal” use with a branded thermal paste the intervals should be somewhere between 4 and 5 years. If the CPU and GPU are cooking the whole time then yeah, 1 to 2 years. But even then, if you’re not a little bit tech savvy, impatient and cautious you can mess up pretty badly…
Oh I just got this 2080ti so maybe about a week ago!
