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.

02.10.2015 - BUG 10/2015 NH-U9S
Test verdict: "Performanse hladnjaka su, s obzirom na njihove gabarite, izvrsne. Pod time podrazumijevamo da će bez problema hladiti većinu procesora koji su trenutno na tržištu, čak i ako se odlučite na overklokiranje." (Denis Arunović;, BUG BUG 10/2015)

01.10.2015 - NH-C14S
Test verdict: "Noctua NH-C14S is a worthy successor to NH-C14 and is even supreme due to its performance, being achieved with one cooling fan out of the box." (Dobrin Krastev,

28.09.2015 - PCGH Extreme Forum NF-P14s redux-1500 PWM
Test verdict: "Für mich sind die redux-Lüfter ein Top Produkt das nur von der 'vollen' Variante übertroffen wird" (Julian Brockmeier, PCGH Extreme Forum)

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."
