I recently aquired an EVGA gtx 760 reference card. I ran Fromark for 1 hr and everything looked ok accept that the stock fan even at idle was loud n cranky. Is there a way to put a custom fan on? I have seen a couple of gpu fans on newegg that look good but my card has a hideously large aluminum heatsink on it with the fan next to that at the end of the card. Can i get rid of the heatsink and put the fan directly on the gpu? Will the shroud go back on? Does it have to go back on?
