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.

I would go with some serious air flow. https://www.amazon.com/Hurricane-Box-Fan-Efficient-Lightweight/dp/B06XGSJ94B/ref=sr_1_1_sspa?ie=UTF8&qid=1529008912&sr=8-1-spons&keywords=hurricane+box+fan&psc=1

and then --IF NEEDED-- something to suspend it in place: https://www.amazon.com/Weaver-Leather-Adjustable-Holder-Black/dp/B004BAXVUQ/ref=pd_sbs_468_3?_encoding=UTF8&pd_rd_i=B004BAXVUQ&pd_rd_r=FH26YR5YYPWSYC1MKKJ6&pd_rd_w=T8A73&pd_rd_wg=R80gc&psc=1&refRID=FH26YR5YYPWSYC1MKKJ6

I know you asked about daisy chain into molex but if you are just going to keep on using little computer fans you aren't really going to change much.

You can keep using the little computer/molex connected fans but if you add the box fan you will move A LOT more fresh air and you don't even have to set it on a high setting. This should work in open air or even a closed chassis which sounds like you have a closed chassis. If you can run the chassis open-air that's even better but I imagine you might have some requirement to keep it closed.

It would help if you could post a picture of your setup so we can see what you are dealing with.

In my situation, I'm lucky enough to keep my stuff in a basement. I run box fans in the summer but no need when it's 0/32 (c/f) degrees in the winter
