ARCTIC F14 PWM 140 mm Case Fan, Signal regulates Fan Speed, quiet motor, Computer, Speed: 200 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 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: 200–1350 RPM, Airflow: 74 CFM/126 m³/h (@ 1350 RPM), Noise Level: 0.3 Sone (@ 1350 RPM), Pin: 4-pin
