The Noctua NF-A20 5V is a large-format cooling fan, measuring 200 mm in diameter and 30 mm in thickness, suitable for specialized chassis ventilation applications. This model is engineered for dedicated 5V input, allowing integration into systems powered by sources requiring lower operating voltages. Performance characteristics include a maximum rotational speed of 800 RPM, generating 147 m³/h of airflow and 1.08 mmH₂O of static pressure. The unit employs the SSO2 bearing system, which contributes to its specified Mean Time To Failure (MTTF) rating of 150,000 hours.
Acoustic output is managed to ensure low operational noise, registering a maximum noise level of 18.1 dB during full rotational speed. The fan incorporates specific aerodynamic features, including an Advanced Acoustic Optimisation (AAO) frame and Flow Acceleration Channels, designed to improve efficiency and minimize the sound profile. Connectivity is provided via a standard 3-pin connector; this model does not support Pulse-Width Modulation (PWM) speed control. The package includes necessary mounting hardware, a USB power adaptor cable, and an OmniJoin adaptor set for installation flexibility across various setups.
