Folding these proteins and even at 90% the temps are around 160F - 168F (that's around 70c). I know HD4870s get hot, but is there a way to cool the card without taking the stock cooler off (and voiding the warranty)?
80mm fan directly blowing on the heatpipes don't do anything, as the heat seems more related to processing (as soon as I stop a WU it'll fall to 120-125F).
Advice?
