Two 120mm full-range user adjustable variable speed fans (800rpm ~ 1300rpm). Fan mounted with vibration-absorbent gaskets to decrease noise resonance. High thermal-efficiency heatsink design allows user to achieve lower CPU temperature without the need for high airflow fan. Included user-friendly mounting mechanism supports all Intel LGA 775 / 1156 / 1366 and AMD AM2 / AM2+ / AM3 CPU sockets. Single backplate for both AMD and Intel applications. Five 6mm heatpipes accelerates heat transfer from the heat source to the heat dissipating fins. Open-frame fan design that effectively decreases overall air-rebounding noise.
