The innovative PWM Sharing Technology – Use PST to control the fan speed

How is the temperature decreased by PST?

Fans using the PWM feature just function with the necessary speed to endure maximum cooling at the lowest noise level.
Thanks to the patented innovative PWM Sharing Technology (PST), up to 5 fans (including CPU fans) connected to the ARCTIC F PWM fan can share the PWM signal. The speed of all the fans in this PST system is then centrally controlled by a single PWM signal via BIOS.
This means if the system load becomes greater, the fan speed of all fans within the PST system increases to reduce the chassis temperature. If the utilization is low, these fans will operate at a relatively low speed to ensure a proper cooling.

All advantages at a glance

  1. Regulate the speed of different fans with only one PWM signal
  2. Quiet and effective case ventilation: Several fans rotate slowly and quietly at a little load.
  3. Save energy through lower fan speed
