SLI 580 Water Cooling help

post #1 of 3
Thread Starter 
I want to OC my two 580's as high as I can but, im not sure how big of a rad I will need to keep my temperatures below 65-70C. This is going to be a gpu only loop my cpu if going into a separate loop. If anyone can give me some ideas would be a great help.

RX360...a 240 may be able to do it as well, but the 360 will give you more headroom and cool just a bit more efficiently.

Why separate Loop? You will need a extra pump and res. All you need is 120 or 240 or you can run both CPU and GPU on a 360 easily since 2500K does not realise much heat.

Edit: Since you have 2 cards then you will need 240-360. Having a 360 will give you at most 2-3C better temps.
