Noctua NF-A9

The NF-A9 is a next-generation, highly optimised, quiet 92mm fan that integrates Noctua's latest aerodynamic innovations to achieve unprecedented low-noise cooling performance. It uses state-of-the-art technologies such as the AAO frame (Advanced Acoustic Optimization) or the Flow Acceleration Channels and has even better silent cooling performance than the award-winning NF-B9. The NF-A9 is characterised by exceptional smoothness, the SSO2 reference bearing from Noctua, a rich package of accessories and is a product of the highest quality. The superior efficiency, innovative construction and groundbreaking materials make it a first-class choice for the most demanding requirements.


The 3-pin FLX version offers a speed setting of 1600/1250/1050 rpm via the included low-noise adapter to ensure full flexibility in the configuration of the fan for maximum cooling performance or almost silent acoustics.
