Noctua NF-A12x25R PWM Case Fan, 120 mm, Beige/Brown

The Noctua NF-A12x25R PWM is a 120 mm fan engineered for applications requiring high static pressure, such as on CPU coolers, radiators, or within cases with restrictive intake vents. Its impeller is made from Sterrox Liquid Crystal Polymer (LCP), a material chosen for its rigidity, which helps minimize blade flex and maintain a tight 0.5 mm tip clearance. This aerodynamic design is intended to improve performance when pushing air against resistance. The fan incorporates Noctua’s SSO2 bearing, a self-stabilizing oil-pressure system that promotes quiet operation and mechanical stability over its lifespan.

This model offers a wide operational range of 450 to 2000 RPM, managed via a standard 4-pin PWM connector for automatic motherboard-based speed control. At its maximum rotational speed, the fan is rated to deliver an airflow of 60.1 CFM and a static pressure of 2.34 mmH2O, with a corresponding noise level of 22.6 dB. For users prioritizing lower noise levels, a Low-Noise Adapter is included to cap the maximum speed. The fan's round-frame design is tailored for certain mounting systems where a square frame may not be compatible.
