The heatsink plate array is topped with a 120x25mm fan. Its blades are covered with protective wire grid:
The fan sits in the heatsink grooves on tuber compensators that should absorb parasitic vibrations and reduce the level of generated noise:
The fan is very easy to remove, so it will be no problem to replace it if necessary. The fan features a four-pin power connector and supports PWM rotation speed management function.
So, the fan rotation speed may vary from ~800RPM to ~1500RPM with maximum 27.2dBA of noise and 56.CFM airflow. The Rifle bearing of the fan is guaranteed to run 40,000 hours.
The protective plastic film on top of the cooler base doesn’t serve any real protective function:
…because the quality of the cooler base finish leaves much to be desired:
