Just did some quick math, based on a 2000rpm, 10 deltaC, my rads have up to 778 watts of heat capacity. My system is around 600 under full load. If i had to guess, playing DA:I puts my system at about 70% load during intense scenes. So say 450 watts to be safe. Put my fans at 1000 rpm and a deltaC of 20 degrees, I have more than enough cooling potential. I think. I could be horribly wrong.
