The NF-B9's highly-optimised 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. Review Review Review Review Review


Bevelled Blade Tips
Due to advanced design measures like the bevelled blade tips, the NF-B9 is surprisingly quiet despite its outstanding airflow and pressure performance.



Vortex-Control Notches
Psychoacoustic optimizations like the Vortex-Control Notches make the NF-B9's noise pattern more pleasant to the human ear.


Smooth Commutation Drive
The new SC drive system reduces torque variations and thereby ensures improved running smoothness, particularly at lower speeds.


Self-stabilizing oil-pressure bearing
Noctua's well proven SSO-Bearing technology guarantees supremely quiet operation and exceptional long-term stability.
