Now a few words about the fan. The fan is fastened in a plastic frame that catches onto the grooves on the sides of the heatsink with plastic hooks:
It is a 92 x 25mm fan with PWM adjustable rotation speed that ranges from 900 to 2400 RPM generating from 10 to 25.8dBA of noise. It creates 45.8 CFM maximum airflow. The fluid dynamic bearing of the fan should last for 50,000 hours of non-stop operation.
The distinguishing feature of this seven-blade fan is four silicon spindles it is installed on:
They absorb parasitic vibrations and prevent them from transferring onto the heatsink. Moreover, GELID Silent Spirit developers stress that according to their research, there should be 5-5.5 mm between the fan and the heatsink for most optimal performance, which is exactly what they did on their Silent Spirit cooler.
Compatibility and Installation
You won’t need to remove the mainboard from the system case to install the cooler onto the board. For AMD platforms you use two retention panels that catch on to the hooks on the standard plastic retention frame, and for LGA775/1366 platforms you use the enclosed push-pin retentions:
There is very little info about the preferable cooler position inside the system case. They only mention that if the cooler is installed so that the heatsink is angled towards the back of the case, the warm air will be quickly removed from around the CPU by the rear case fan. If you case also has a fan at the top, then you can install the cooler like this:
The MSRP for GELID Silent Spirit is set at $35.
