Noctua - Bild

Product discontinued.

The classic NF-B9 92mm fan helped to found Noctua’s reputation as a top-tier manufacturer of premium quality quiet cooling components and still impresses users with its exquisite quietness and superb performance. The new PWM version features Noctua’s novel, custom designed PWM IC for fully automatic control and ultra-low power consumption. Equipped with Noctua’s signature SSO bearing and topped off with a 6 years manufacturer’s warranty, the NF-B9 PWM is a proven premium choice for the highest demands.



Focused Flow Proven NF-B9 Design
Tens of thousands of quiet cooling enthusiasts swear by Noctua’s classic NF-B9. Its impressive quietness, excellent performance and impeccable, time-tested quality made the B9 a default choice for 92mm quiet cooling.

Bevelled Blade Tips Bevelled Blade Tips
Reducing critical rotor stator interaction, the NF-B9’s Bevelled Blade Tips permit to combine a higher blade surface area with quieter operation and thus form a cornerstone of the fan’s outstanding efficiency. button

Vortex-Control Notches Vortex-Control Notches
Noctua’s signature Vortex-Control Notches split up trailing edge vortices and thus spread the fan’s noise emission over a wider range of frequencies. This measure makes the NF-B9 PWM sound more pleasant to the human ear. button

PWM Custom designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NF-B9 PWM uses Noctua’s novel, custom designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at lower speeds. button

LNA Low-Noise Adaptor
The NF-B9 PWM is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the maximum fan speed from 1600 to 1300rpm. The L.N.A can be used either to run the fan at a fixed speed of 1300rpm or to cap the maximum speed when using automatic PWM control.

Cabling Options Extensive Cabling Options
The fan’s short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and a 4-pin y-cable allows to connect a second NF-B9 fan to the same PWM fan header for automatic control.

SSO-Bearing SSO-Bearing
Combining the proven concept of hydrodynamic bearing with an additional magnet that supports the self-stabilisation of the rotor axis, Noctua’s time-tested SSO-Bearing technology has become synonymous with supremely quiet operation and exceptional long-term stability. button

Warranty 6 years manufacturer’s warranty
Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-B9 PWM features an MTBF rating of more than 150.000 hours and comes with a full 6 years manufacturer’s warranty.

Test verdict: "The Noctua NH-D9L packs alot of cooling in a little package. If you are needing to save the space but do not want to sacrifice performance the dual fan setup competes pretty close to the big behemoth coolers." (Chris McCart, FunkyKit.com)

Test verdict: "Overall, I believe Noctua makes an excellent product. There really isn’t anything I can complain about except for the price, and even then the price is understandable. If you need good air flow, low noise and have a small form factor case that needs some better fans, I could definitely recommend what Noctua has to offer here." (Josh Jackson, PureOverclock.com)

03.03.2015 - FrostyTech.com NH-U9S
Test verdict: "Given these height and footprint size restrictions, the Noctua NH-U9S is a pretty quiet heatsink that offers very good thermal performance in the sub-125mm tall heatsink category, making it an excellent choice for PCs which are severely space limited. The results are enhanced by adding a second fan, as we've shown over the course of this review. Couple that with awesome build quality and a 6 year warranty and it's not hard to recommend this cooler." (Max Page, FrostyTech.com)

02.03.2015 - Hardwareluxx Community NF-P14s redux-1200 PWM
Test verdict: "Das Ergebnis dieses Reviews zeigt, wie effizient die Redux tatsächlich arbeiten. Auch wenn es sich hierbei nur um 0,15 bis 4,05°C handelt. Die Lautstärke ist bei voller Drehzahl im Vergleich zum TY-147A wesentlich geringer [...]. Für einen angemessenen Preis von ca. 13 Euro bietet Noctua einen erstklassigen und sehr qualitativen Lüfter." (Aliriza Tasdemir, Hardwareluxx Community)
