Noctua NF-P12 redux-1700 PWM 120 mm Case Fan - Grey

The Noctua NF-P12 redux-1700 PWM is a 120 mm case fan designed for efficient system airflow and cooling. It connects via a standard 4-pin header, enabling Pulse Width Modulation (PWM) for automatic speed control through the motherboard. This function allows the fan's rotational speed to dynamically adjust anywhere between its 450 RPM minimum and 1700 RPM maximum. Such a range provides quiet operation during low loads and increased cooling performance when system temperatures rise. The fan also includes speed detection, which lets system monitoring software report its operational RPM in real time.

This fan is constructed from PBT GF30 material and utilizes a hydraulic bearing for consistent operation. At its maximum rotational speed, it is specified to generate an airflow of 70.75 CFM and a static pressure of 2.83 mmH2O. The corresponding noise output at this speed is 25.1 dB. Its standard 120 x 120 x 25 mm frame ensures physical compatibility with most PC case fan mounts. The unit is supplied with four standard mounting screws for straightforward installation into a computer chassis.
