Product Overview

The Noctua NF-A12x25 PWM is a 120 mm, 4-pin PWM fan that suits cases, CPU coolers and radiators. It combines the AAO (Advanced Acoustic Optimisation) frame and Flow Acceleration Channels with an impeller gap of just 0.5 mm. The fan runs from 450 to 2,000 RPM, moving 84.5 to 102.1 m³/h of air at 18.8 to 22.6 dB, on an SSO2 bearing.

Noctua’s A-series design aims to work in both low-resistance case ventilation and high-resistance setups such as heatsinks and water-cooling radiators. Automatic speed control runs over a PWM header, and the included Low-Noise Adapter lowers the maximum speed from 2,000 to 1,700 RPM. The box also holds a 30 cm 4-pin Y-cable extension, NA-AV2 anti-vibration mounts, an anti-vibration gasket for radiators and fan screws.
