Benchmark Reviews has the SilverStone SST-AR01 strapped to the test bench today for a little review action. For comparison purposes, you can see our evaluation here. At the end of the day, the AR01 performs its function adequately. It'll keep an FX CPU cool, so it should keep almost every other CPU cool as well. The installation was comparable to other products, and the fan mounting system was the best I've had a chance to work with.
