ARCTIC F9 PWM - 92 mm PWM Fan, Silent CPU, PWM Technology Control, Push and Pull Configuration, Fan 150-1800 RPM - Black

INNOVATIVE DESIGN: Innovative blade design improves airflow and the possibilities for more efficient ventilation. The fan has been designed to make as little noise as possible FAN ADJUSTMENT: The PWM function signals via the motherboard at what speed the fan should run. This ensures maximum cooling performance with minimum noise LONG LIFE: The hydrodynamic sleeve bearing features an oil capsule to prevent loss of lubricant. As quiet as a smooth bearing, but with a much longer service life DUAL MODE INSTALLATION: You can expel hot air out of the case or draw fresh air into the case. Fan with standard housing TECHNICAL DATA: Fan speed: 150-1800 RPM, Air flow: 43 CFM / 73.1 m³ / h (@ 1800 RPM), Noise level: 0.4 Sone (@ 1800 RPM), Pin: 4-pin
