Review on Noctua NF-P12 redux-1300 PWM Quiet Fan - Ultimate Performance at 1300 RPM (120mm, Grey) by Marco Habersham

This fan is ideal for pressure-optimized airflow. For example, a front mesh air intake or a cooling tower. This fan is on the right in the first photo. I have a second one at the bottom of my P400A's air intake. Below are 2 140mm Noctua fans of the same type. (This P400A normally fits 3 x 120mm in front or 2 x 140mm - with a little tricky workflow you can fit 2 x 140mm and 120mm in front for extra airflow!) Size: 120 x 120 x 25mm -optimized nine-blade- Design with vortex control notches 1700 rpm max. rotation speed (+/- 10%) 450 rpm min. rotation speed (PWM, +/-20%) Air flow: 120.2 m³/h Noise level: 25.1 dB (A) Static Pressure: 2.83mm H₂O Package Contents: NF-P12 x1 and Fan Screws x4 Warranty: 6 years
