Noctua - Bild

Product discontinued.

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. Bevelled blade tips, Vortex-Control Notches as well as Noctua's SCD drive system and premium-grade SSO-Bearing ensure outstanding quietness and long-term stability.
