Arctic Cooling 9PWM 90mm High Performance Ultra Quiet PWM Case Fan with 4 Pin Connector

The case ventilation system in lockstep, the CPU gives the beat. The ARCTIC F PWM is forwarding the PWM signal from the CPU to the whole case ventilation system. This way, the entire system is cooled quietly, but still offers the performance, when needed. With the standard 25mm frame, the ARCTIC F PWM can be applied as sucking and blowing system fan. Thanks to fluid dynamic bearing and the patented fan holder design, the ARCTIC F PWM is not only quiet, but also highly durable. Via the PWM signal, the CPU fan is controlled by the mainboard to reach the ideal temperature for the CPU. The patented PST (PWM Sharing Technology) is forwarding the PWM signal to all other fans inside the system. This way, all fans are spinning at the same speed. This provides silent operation in idle mode, but also gives sufficient performance, when required to offer efficient cooling.
