The Ultra Quiet AK-955V2 uses a hi-engineered omni directional heatsink with full length ventilated copper core. The new design fan frame provides side ventilation which increases air induction.  Bi-ped fins maximise heat dissipation. 

The fan uses INTEL approved power management (PWM) with auto fan operation. The PWM fan speed is regulated by CPU usage. This means under normal operating conditions, the CPU fan speed is relatively low. Adjustable push-pins for easy mounting and reliable retention on LGA775 / 115X.
