Exhaust Fan Suggestion

[varstas]

Hi, I've just built my new pc but i have problems regarding of cooling. I'm using CM Masterbox K500l and inside ryzen 2700x with stock cooler, asus rtx2080, msi pro carbon x470, CM 600w 80+ psu.

There are 2 12mm front fans and 1 12mm rear exhaust fan. All of these fans are preinstalled and they are total garbage. Front red led fans are noisy no pwm control and rear exhaust do nothing in terms of throwing hot air outside.

 

Let me share my tests so you can understand my problem better. 

After playing Division 2 for 1 hour with max settings on 2k; GPU 74C and CPU 80C.

After playing Division 2 for 1 hour with max settings on 2k with left side of the case is open; GPU 64C and CPU 62C.

 

After this i believe what i need is a good exhaust. I'm planing to place this fan on top side of the case. Can you give me any recommendation of 120mm fan?

You def have bad case cooling if it drops that much opening the side panel.  54c must mean your fans are on full or you have a really ambient room temp.  That is un heard of unless your water cool the GPU.  I get 67 or 69c with fans at 70 percent I could barely hear it when gaming.  Also 62c is better then normal.  Its exceptional temp for CPU on load.  I guess leave your side panel open until the weather gets cooler, but were headed into summer so just keep your side door open, until winter then perhaps you can close the case, which I don't think you should do.  Those temps are insane.  Can you post a pic of your case ?  Outside shot and inside shot.  Thanks

Ah, you see here's your problem. They're a bit too small.

 

 

In all seriousness, you'll want fans that push more air in than out, positive air pressure is usually better for dust and whatnot. Look for fans with a higher cfm number.

I'm sorry this was a typo. GPU down to 64 not 54 on left side open. I'm adding the pictures of my case.

Quick update: I have changed stock cooler with CM ML240R. Now CPU never past 55C. I have also ordered 2 Noctua NF-S12A as exhaust fan, 1 rear 1 top, to cool down the GPU too.

According to LMG Luke, two (or three) in and two out, as you suggest that you are doing, is the best setup.
