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

This 200 mm diameter case fan is engineered for high-efficiency cooling in large computer chassis. The unit operates within a rotational speed range from a minimum of 350 RPM up to a maximum of 800 RPM, regulated via a standard 4-pin PWM connection. At peak velocity, the fan moves air at a rate of 146.9 m³/h (86.46 CFM) while generating 1.08 mmH2O of static pressure. Its construction includes an advanced SSO2 bearing, contributing to a high mean time between failures (MTBF) rating of 150,000 hours.

The operational profile prioritizes low acoustic output, registering a maximum noise level of 18.1 dB. Minimum noise generation is measured at 10.7 dB when operating at the lower speed threshold, suitable for systems where quiet performance is critical. The fan requires a 12V power source and consumes 0.96 W under typical usage. The 30 mm thickness is designed for compatibility with chassis mounting points that support large-format fans.
