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.

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.

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

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

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.

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

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

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.
