Noctua NF-A20 PWM Fan, SSO2 Bearing, 200mm, Brown/Beige

This PC cooling component is a 200 mm diameter fan designed for high-volume case airflow, utilizing a 30 mm thickness profile suitable for large chassis installations. It operates within a rotational speed range of 350 RPM minimum up to 800 RPM maximum, controlled via the integrated 4-pin PWM connection. At peak output, the fan delivers 146.9 m³/h (86.46 CFM) of airflow and generates 1.08 mmH2O of static pressure. This configuration ensures efficient air movement across the component area. The fan maintains a maximum noise output of 18.1 dB at its highest rotational speed.

The unit employs Noctua's proprietary SSO2 bearing technology, which is designed to provide sustained stability and a long operational lifespan rated at 150,000 hours MTTF. Construction utilizes durable PBT GF30 material for the frame and PP GF10 for the nine-bladed impeller. Users are supplied with a Low-Noise Adaptor (L.N.A.) to further reduce the operational speed maximum to 550 RPM, decreasing acoustic output to 10.7 dB. The fan operates at a rated voltage of 12V and consumes 0.82W of power.
