ARCTIC F12 PWM - 120 mm PWM Case Fan, PWM-Signal regulates Fan Speed, Very Quiet Motor, Computer, Fan Speed: 230-1350 RPM - Black

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
TWO WAY INSTALLATION: Blow warm air out of the case, draw cool air into your case
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\u20131350 RPM, Airflow: 53 CFM/90.1 m³/h (@ 1350 RPM), Noise Level: 0.3 Sone (@ 1350 RPM), Pin: 4-pin
