Features

 

  • 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.
