ARCTIC F12 PWM PST (2 Pack) - 120 mm PWM PST Case Fan with PWM Sharing Technology (PST), Value Pack, Very Quiet Motor, Computer, Fan Speed: 230-1350 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: 230–1350 RPM, Airflow: 53 CFM/90;1 m³/h (@ 1350 RPM), Noise Level: 0;3 Sone (@ 1350 RPM), Pin: 4-pin
