Case fans air flow.

[nph]

Hello.

I recently bought new pc with RTX 3060 Ti and Fractal Design Define 7 Black that has 3 preinstalled 140mm fans. I noticed when I dont play games and only watch stream or videos that my gpu nonstop reach 60 temperature and the fans turn on, then it goes down around 40 and it slowly reaching back to 60 and fans start again. The thing is when I put my hands in front of GPU the air from front fans don't reach the gpu at all. Is that okay, or is there a way to make case fans go faster ?

Depends. If they're motherboard controlled, there should be some settings in the BIOS to kick them up a bit. But if options are limited, you may want to get a fan controller. I run a Corsair setup and it is awesome.

 

That said, the Define 7 has a very limited air intake capacity and it is going to build a little heat. A more open-faced case like the Pop Air / XL or Focus G / Mini would help this a bit. But it also appears the Define 7 supports topside fans and if you don't have any topside, that may help stabilize temps a bit more.

Nah that pos is an oven, i mean look at the dinky ass intake, it look like it can barely take any air in

I wouldn't say all that... Is the Define 7 ideal for airflow? No, but it can cool with some help. I ran my 5900X / RTX3060ti in a Corsair 4000X and it didn't have much more intake. Took six 120s and a Scythe Mugen 5 to cool it in there, but it peaked around 80-85 on CBR23. Otherwise it peaked around 75-76C, idled around 34-38. Though I will say that after some fan curve adjustments, it runs about 5-15C cooler in the Pop XL Air.

 

OP, I say install a couple 120s topside exhausting upwards, or get a fan controller and set up an aggressive fan profile, say about 45% to 65% from 40-75C, and 75-85% from 75C+. You can get three-way splitters for PWM, I run six SP120s on an ASRock B450M-HDV's two headers and it works fine. Peaks around 60 even gaming with a 3600X.

It does better than you'd think. More so on the GPU temps than CPU temps. CPU temps are meh.

If your case fans are plugged into the motherboard, you can go into BIOS and set your fan curves to be more aggressive, or at least to not cut out around 40.

Your hand is not a good tool for measuring airflow. 

If temps are fine, there's enough airflow.

I found some settings in bios but I really don't know how it works.

Try all full speed if you want quick easy test. I would also take a look in hwinfo64 to see what kind of watts your gpu has when in idle. Sometimes multi-monitor idle is 20W:s and that means the semipassive system wont work well and keeps doing that annoying cycle of start&stop.

I already tried set fans at full speed but it sounds like an airplane.Also I downloaded the hwinfo64 and idk if this is it but I post it here.

That's just an oven of a case. Deal with the temps and move on

I mean it's not a big problem for me, I just wonder If the gpu wil not mess up or something if it's nonstop going to 62 fans start, then it drops back to 40 something fans stops and the same again and again.

Should be perfectly fine in idle.

You can do a custom fan curve for the gpu. You dont need high speed in idle to keep it under 40C.

I watched some video how to do it but im afraid I will break the gpu or something. Also I found out that I can set the case fans speed with MSI Center, maybe I'll play with that and see how it goes.

 

Edit: I managed to set fans from 50 to 75 and the GPU is between 55-58 temperature idle, so i'm satisfied now. At least it doesn't pop gpu fans every 20 minutes.
