Aer F 120mm PWM Fan - Twin Pack NZXT presents the Aer F, a powerful fan for efficient air circulation within any case. Its high-quality fluid dynamic plain bearings ensures a particularly long service life. The PWM fan comes with a 4-pin connection can be conveniently controlled. To visually adapt the fan, NZXT offers interchangeable coloured frames (not included). The NZXT Aer F Features: Impressive air throughput of 21. 01 63. 02 CFM Extremely high air pressure of 0. 13 to 1. 24 mm H2O Volume of 22 31 dB (A) Connection via 4pin PWM connector Fluid dynamic plain bearings for long durability Powerful fan in 120 mm format The Aer F fan delivers optimal airflow with high durability. Thanks to the angled air inlets and outlets the so-called \"winglet\" fan blades air resistance is minimized and increases the fan performance. As a result, the PWM fans produce an excellent air flow rate of up to 63 CFM and an air pressure of 0. 13 - 1. 24 mm H2O. Due to the fluid dynamic bearings used, the Aer-F fans even have an extended service life of more than six years. In addition, they ensure an ever-uniform lubrication, which significantly reduces the noise, as well as by the vibration damper, during operation.
