Arctic F12 PWM PST pack of 5

Long operating time: the hydrodynamic plain bearing is equipped with an oil capsule so that a loss of lubricant is avoided PWM regulation: the PWM function signals via the motherboard at which speed the fan needs to run. This ensures maximum cooling performance with minimal noise level PWM SHARING TECHNOLOGY (PST): PST ensures that all fans work on one signal. Parts 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: 230-1350 rpm, air flow: 53 CFM/90.1 m³/h (@ 1350 rpm). ), Noise level: 0.3 Sone (@ 1350 rpm. Pin: 4-pin
