ARCTIC F9 PWM PST ACFAN00214A

F9 PWM PST 92 mm PWM PST Case Fan 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 significantly higher service life. 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) LOWERS NOISE - If you want to improve the cooling efficiency of your computer you get several case fans working in parallel (since it takes 10 fans to double the noise level). But what does it help if they don't work together? The 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. INNOVATIVE DESIGN ENABLES QUIET AND EFFICIENT VENTILATION - The innovative design of the fan blades improves the air flow and facilitates a highly efficient ventilation. The impeller was designed with a focus on minimzing the noise level yet delivering the desired airflow and pressure. TWO WAY INSTALLATION - Blow warm air out of the case. Draw cool air into your case TECHNICAL SPECIFICATIONS Performance Fan Speed 150 - 1800 rpm Airflow 43 CFM/ 73.1 m3/h Static Pressure 1.35 mm H2O Noise Level 0.4 Sone Operating Ambient Temperature 0 - 40 °C Fan Fan Frame Standard Control Type PWM PST Connector 4-Pin-Connector + 4-Pin-Socket Fan Bearing Fluid Dynamic Bearing Electric Characteristics Typical Voltage 12 V DC Starting Voltage 8.5 V Current/Voltage 0.15 A / 12 V Cable Lenght 400 mm Size & Weight Length 92 mm Width 92 mm Height 25 mm Weight 85 g .
