“When looking for a heatsink or cooler there are a few things you want to look for. Normally look for one which is copper or copper/aluminum combination, but this will increase the cost. This heatsink is all aluminum but it utilizes 8 towering heatpipes and countless fins. This more than makes up for it not being copper, although if it were copper the performance would probably be even better. That being said, the performance of this heatsink is excellent and that's what counts…” ~3dGameMan.com
