How does PST lower temperatures?
Fans using the PWM feature operate with only the necessary speed to enable 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 load is low, these fans will operate at a relatively low speed to ensure proper cooling.
- Regulate the speed of different fans with only one PWM signal
- Quiet and effective case ventilation: several fans can rotate slowly and quietly with low loads
- Save energy through lower fan speed
