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.

BBT 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. button

VCN Vortex-Control Notches
Psychoacoustic optimizations like the Vortex-Control Notches make the NF-B9's noise pattern more pleasant to the human ear. button

SCD Smooth Commutation Drive
The new SC drive system reduces torque variations and thereby ensures improved running smoothness, particularly at lower speeds. button

SSO Self-stabilizing oil-pressure bearing
Noctua's well proven SSO-Bearing technology guarantees supremely quiet operation and exceptional long-term stability. button

25.09.2015 - NH-D9L
Test verdict: "Mais uma vez, a Noctua não tem intenções de parar e fez um excelente trabalho que junta a eficácia e a qualidade em apenas um só. O Noctua NH-D9L é um cooler com apenas 11 centímetros que junta compatibilidade, qualidade e performance, fazendo-o assim um dos principais coolers para configurações mATX ou abaixo desta."
