Home > Noctua Case Fans >Noctua NF-B9 92mm 17.6dB 7 Blade Quiet Case Fan - OEM (no box)
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. The Noctua NF-B9's vevelled blade tips, vortex control notches, as well as Noctua's SCD drive system and premium-grade SSO-bearing, ensure outstanding silence and long-term stability.
Due to advanced design measures like the bevelled blade tips, the Noctua NF-B9 is surprisingly quiet despite its outstanding airflow and pressure performance.
Psychoacoustic optimizations like the Vortex-Control Notches make the NF-B9's noise pattern more pleasant to the human ear.
The new SC drive system reduces torque variations and thereby ensures improved running smoothness, particularly at lower speeds.
Noctua's well proven SSO-Bearing technology guarantees supremely quiet operation and exceptional long-term stability.
