Product details

Thanks to its Advanced Acoustic Optimization frame system and advanced aerodynamic design features like Flow Acceleration Channels, the NF-A20 offers the renowned excellent silent cooling performance of Noctua's award-winning A-series, now available for the first time in a 20 cm format. The FLX version allows for two speed settings (800/550 rpm) via the included Low-Noise Adapter, providing full flexibility between maximum airflow and nearly silent operation. Its superb smoothness, the SSO2 reference-class bearing, and Noctua's proven premium quality make the NF-A20 a top solution for the highest demands.
