Noctua Nf-A9 Flx

Thanks to Noctua's AAO (Advanced Acoustic Optimization) frame system and advanced aerodynamic design features such as Flow Acceleration Channels, the NF-A9 offers even better silent cooling performance compared to the multiple award-winning NF-B9. The FLX version provides three speed settings (1600/1250/1050rpm) via the included low-noise adapters, ensuring 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-A9 FLX an outstanding solution for the highest demands.
