Hey all. I tried to search the forums here and couldn't find exactly what I was searching for. Basically, I set up a 6 GPU rig recently and can't figure out how to cool down the GPU's adequately. What I have is: 6 XFX RX580 and 3 fresh air fans coming in and 3 fans going out of the chassis. I also set the fans on each GPU to go to 100% at 75C. Even with all of this, I am running at 87-89C consistently. And from what I understand, this is going to either burn my cards up or create a fire hazard. So, two questions: 1) can anyone recommend a very high air flow fan that I can daisy chain with 4 pin molex and 2) any software tweaks I can use outside of afterburner? After spending a butt load of money, this rig is going to be a paper weight if I can't cool down my cards. Thanks for the help.
