The card with the best performance from AMD from the previous generation, the ATI RADEON 4870X2 has a very noisy stock cooling cooling system. Surprisingly, not a lot of custom VGA coolers appeared for it. Arctic Cooling thought a lot of us, the 4870X2 users and released the Accelero XTREME 4870X2 after a very big delay. Will this custom cooling be as great as it says on the package? We will see later in this review.
