Noctua NF-A12x25 PWM 120 mm Case Fan - Beige, Red

The Noctua NF-A12x25 PWM is a 120 mm fan designed for PC cooling applications that require high static pressure and airflow, such as on heatsinks and liquid cooling radiators. Its fan blades are constructed from Sterrox liquid-crystal polymer (LCP), a material selected to reduce blade resonance and deformation at high rotational speeds. The unit incorporates a second-generation Self-Stabilising Oil-pressure (SSO2) bearing to enhance operational stability and lifespan. The frame and rotor are engineered to maintain a minimal tip clearance, which improves performance when the fan is working against back pressure.

This fan supports Pulse-Width Modulation (PWM) for automatic speed control via a standard 4-pin motherboard header. Its rotational speed ranges from 460 RPM at its minimum to 2000 RPM at its maximum setting, allowing for a balance between low-noise operation and cooling performance. At full speed, it generates an airflow of 60.09 CFM and a static pressure of 2.34 mmH₂O. The package includes a Low-Noise Adaptor (L.N.A.) to cap the maximum speed, as well as anti-vibration mounts and a gasket for radiator installation.
