The PWM chip in the motor allows an exact fan speed control over the BIOS (4 wire).
The Fluid Dynamic Bearing keeps oil inside the bearing and thus reduce friction inbetween and keeps the noise level to a minimum. The four rubber connectors on the fan case act as a vibration damper to absorb the vibration of the running fan and prevent vibration transfer to the heatsink and the case.
The low speed 92 mm fan reduces the noise level to a minimum. The patented fan holder is able to practically eliminate the typical buzzing sound of 92 mm fans.
