Anyone with an ATI 5970 knows by now that the card can begin to run very hot if it is not properly ventilated. This heat will only be compounded if the card is overclocked. Even for users running their cards at stock clocks, a very long gaming session can leave the card running desperately hot, ultimately leading it to an early grave. To counteract noise concerns, but still keep the cards running cool, Arctic has come up with a cooler for the 5970 that dissipates more heat than the 5970's stock cooler, even though Arctic's claim of heat removal is less than that stated by ATI's reference cooler. We will investigate if the Arctic Accelero Xtreme 5970 has what it takes to keep our 5970 cooler than the reference heat sink.
