Please note:  This model has been phased out by Noctua and has been replaced by the new NF-A9 FLX.


After the successful introduction of the NF-P12 120mm fan in November, Noctua presented today their first 92mm retail fan: The NF-B9 complements Noctua's much acclaimed 80 and 120mm fan series, which have been recommended by over 150 international websites and magazines, and achieves outstanding airflow and pressure performance at exceptionally low noise levels.

The NF-B9's highly-optimized blade design achieves an exceptional level of airflow and static pressure that most other fans can only reach at much higher speeds. Bevelled blade tips, Vortex-Control Notches as well as Noctua's SCD drive system and premium-grade SSO-Bearing ensure outstanding quietness and long-term stability.

The NF-B9 has been specifically developed for applications such as CPU coolers that demand superior pressure and airflow performance. Thanks to psychoacoustic optimizations like the Vortex-Control Notches, the new SCD Drive System and Noctua's premium-grade SSO-Bearing, the NF-B9 achieves exceptional quietness and long-term stability.
