ARCTIC F9 PWM PST - 92 mm Case Fan with Sharing Technology (PST), quiet motor, Computer, Speed: 150-1800 RPM Black, White

INNOVATIVE DESIGN: Design of fan blades improves airflow and facilitates efficient ventilation, impeller was designed with a focus on minimzing the noise level yet delivering the desired airflow and pressure PERFECT CASE FAN REGULATION WITH PWM: The PWM function allows the motherboard to run the fan precisely at its necessary speed, this guarantees the required cooling and minimizes the noise level PWM SHARING TECHNOLOGY (PST): PST assures that all of your fans listen to one control signal, e.g. you share the CPU Cooler's PWM signal and assure that your case fans stand down at low load and spin up whenever necessary LONG SERVICE LIFE: The Fluid Dynamic Bearing comes with an oil capsule that avoids lubricant leakage, thus this bearing is as quiet as a sleeve bearing but comes with a higher service life TECHNICAL DATA: Fan speed: 150–1800 RPM, Airflow: 43 CFM/73.1 m³/h (@ 1800 RPM), Noise Level: 0.4 Sone (@ 1800 RPM), Pin: 4-pin
