Noctua NF-B9-1600 (Fan)

   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.

	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.
