The 1600rpm version is ideal for efficient case ventilation or other applications that demand an even balance of performance and quietness.
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.
| 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. |
| Combining the proven concept of hydrodynamic bearing with an additional magnet that supports the self-stabilisation of the rotor axis, Noctua's time-tested technology has become synonymous with supremely quiet operation and exceptional long-term stability. |
| 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. |
