Tweaknews posted a review on the Apack Zerotherm CF900 Copper Heatpipe Intel Socket 775 CPU Cooler

Granted, the ZEROtherm CF900 isn't up to the task for maximum effort overclockers, but that's not its target. No gimmicky design elements, no LEDs, just solid, quiet everyday performance. The CF900 would be an excellent choice for any application where good cooling and quiet operation are necessary. Its compact size only adds to its appeal.
