Proven NF-B9 design

Tens of thousands of quiet cooling enthusiasts around the globe swear by Noctua's classic NF-B9. Thanks to its impressive quietness, excellent performance and impeccable quality, the NF-B9 has become an established reference for quiet 92mm fans.

Vortex-Control Notches Noctua's signature Vortex-Control Notches split up trailing edge vortices and thus spread the fan's noise emission over a wider range of frequencies. This measure makes the fan sound more pleasant to the human ear.	SSO-Bearing Combining the proven concept of hydrodynamic bearings with an additional magnet that supports the self-stabilisation of the rotor axis, Noctua's time-tested SSO-Bearing technology has become synonymous with supremely quiet operation and exceptional long-term stability.	Bevelled Blade Tips Reducing critical rotor stator interaction, Bevelled Blade Tips permit to combine extended leading edges and a higher blade surface area with quieter operation and thus form a cornerstone of the fan's outstanding efficiency.
