FAQ & Section Info
What is a PWM Fan?
Pulse Width Modulation (PWM) is an analog method for controlling motor speed. PWM fans are able to be controlled automatically by compatible motherboards. Responding to temperatures of different compenents and heat sensors installed in the system, the fans are made to run at higher or lower RPMs to provide appropriate cooling for high temperatures and power saving when temperatures are low. PWM fans are compatible with 4-pin fan power connectors.
Are 90mm and 92mm fans the same?
92mm and 90mm fans are slightly different, but for most purposes are interchangeable. It is more advisable, however, to use 92mm fans with 92mm fan mounts, and the same with 90mm fans.
