Conclusion

Arctic Cooling Accelero XTREME 4870X2 is a truly super-powerful cooler for a super-fast graphics accelerator. It leaves the default Radeon HD 4870 X2 cooling solution absolutely no chances of competing even at minimal fan rotation speed neither in efficiency, nor in acoustics. Its installs simply and intuitively, and the rapidly addressed issue with short retention screws indicates that Arctic Cooling cares a lot about their customers. I can’t find any serious issues with this solution, because there are actually none. Large size? High price? Most likely only theoretical compatibility with CrossFireX configurations? All these would be really far-fetched, because the Radeon HD 4870 X2 owners definitely knew what they were getting themselves into when they purchased a large and hot graphics card like that. That is why they will easily agree to these minor inconveniences for the sake of having Accelero XTREME 4870X2. And I am absolutely sure that the cooler we tested today will prove totally up to their expectations.
