OPTIMISED FOR STATIC PRESSURE: The fan guarantees extremely efficient cooling, even with increased air resistance, therefore, the P12 is particularly suitable for use on heatsinks and radiators HIGH QUALITY BEARING: Thanks to an alloy/lubricant combination developed in Germany, friction within the bearing is reduced and greater efficiency is achieved INNOVATIVE DESIGN: 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 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: 1800 RPM, Airflow: 56.3 CFM/95.65 m³/h (@ 1800 RPM), Noise Level: 0.3 Sone (@ 1800 RPM), Pin: 3-pin
