The <b>Deepcool Gammaxx 400 CPU Air Cooler</b> comes with four heat pipes attached to a large heatsink and a 120mm blue LED fan to cool processors. The heat pipes have a direct contact to the surface of your processor to better draw heat away. The heat is cooled via a variable speed fan that spins between 900 and 1500 rpm. The fan provides an air flow of 74.34 CFM and is built with a hydro bearing. To improve cooling performance, the Gammaxx 400 includes fan clips to support an optional second fan.
