The ARCTIC F8, F9 and F12 are exceptionally quiet and cost effective. The patented low noise impeller maximize the airflow, offering high performance at relatively low fan speed.
Color:2) F9 PWM PST (92 mm) Long Service Lifer / 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. r / r / Innovative Design Enables Quiet and Efficient Ventilationr / 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 minimizing the noise level yet delivering the desired airflow and pressure. r / r / Two Way installationr / Blows warm air out of the case and can also draw cold air into the case to fulfil your preference on the airflow pattern within the PC case. r / r / Fan Speed: r / 1,800 RPM (@ 12 V DC)r / 1,200 RPM (@ 7 V DC)r / 800 RPM (@ 5 V DC) r / Air Flow: 43 CFM / 73.1 m³/h (@ 1.800 RPM)r / Noise Level: 0.4 Sone (@1.800 RPM)r / Connector: 3-pinr / Warranty: 6 years limited (Contact Manufacturer ARCTIC)
