Inno3D Watercooled GTX480 iChill Black Series Review
 

Watercooling the GTX480 is a night and day difference in temperatures. Load temperatures are dropped 36oC (!) degrees and idle temperatures are dropped 22oC. The watercooled card is only 5 degrees warmer under full load than the stock cooler managed to keep the card at idle!
