The Noctua NF-B9 quiet case fan includes a highly-optimized blade design which achieves an exceptional level of airflow and static pressure, that most other case 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 silence and long-term stability in a case fan.
Due to advanced design measures like the bevelled blade tips, the NF-B9 is surprisingly quiet despite its outstanding airflow and pressure performance.
Psychoacoustic optimizations like the vortex-control notches make the Noctua NF-B9 quiet case fan'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.
