ARCTIC F9 PWM PST (5 Pack) - 92 mm PWM PST case fan, case fan with PST connector (PWM sharing technology), regulates RPM synchronous, 150-1800 rpm.

Long operating time: the hydrodynamic plain bearing is equipped with an oil capsule so that a loss of lubricant is avoided Perfect fan regulation thanks to PWM: the PWM function signals exactly what speed the fan needs to run via the motherboard. This ensures maximum cooling performance with minimal noise level PWM SHARING TECHNOLOGY (PST): PST ensures that all fans work on one signal. Split the CPU cooler PWM signal and make sure that the fans only turn up/down if necessary Innovative design for quiet and efficient ventilation: the innovative design of the fan blades improves air flow and the possibilities for significantly more efficient ventilation Technical data: fan speed: 150-1800 rpm, air flow: 43 CFM/73.1 m³/h (@ 1800 rpm). ), Noise level: 0.4 Sone (@ 1800 rpm. Pin: 4-pin
