The ARCTIC F PWM fans outperform other 80mm/92mm/120mm fans in the market. The patented PWM Sharing Technology (PST) regulates the speed up to 5 fans via BIOS. With efficient central cooling the ARCTIC F PWM fans offer excellent cooling and noise control performance for the system. Featuring PWM function the ARCTIC F PWM fans run at the most necessary speed to deliver maximum cooling capacity at the lowest noise level possible. On top of that thanks to the patented innovative PWM Sharing Technology (PST) up to 5 fans (including CPU fans) can be connected to the ARCTIC F PWM fan to share the PWM signal. The speed of all the fans in this PST system is now centrally controlled by a single PWM signal via BIOS.
