Noctua 92mm Premium PWM Fan # NF-B9 PWM
The classic NF-B9 92mm fan helped to found Noctuas 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 Noctuas novel, custom designed PWM IC for fully automatic control and ultra-low power consumption. Equipped with Noctuas signature SSO bearing and topped off with a 6 years manufacturers 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 Noctuas 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 Reducing critical rotor stator interaction, the NF-B9s Bevelled Blade Tips permit to combine a higher blade surface area with quieter operation and thus form a cornerstone of the fans outstanding efficiency.
Vortex-Control Notches Noctuas signature Vortex-Control Notches split up trailing edge vortices and thus spread the fans noise emission over a wider range of frequencies. This measure makes the NF-B9 PWM sound more pleasant to the human ear.
Custom designed PWM IC with SCD Supporting fully automatic PWM speed control, the NF-B9 PWM uses Noctuas 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.
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.
Extensive Cabling Options The fans 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 Combining the proven concept of hydrodynamic bearing with an additional magnet that supports the self-stabilisation of the rotor axis, Noctuas time-tested SSO-Bearing technology has become synonymous with supremely quiet operation and exceptional long-term stability.
6 years manufacturers 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 manufacturers warranty.

Note: PWM Fans are not variable speed control fans on their own. An integrated circuit varies the speed and airflow of a fan using a pulse-width-modulated (PWM) voltage in response to temperature or system commands send typically by a computer motherboard. You can use them to run at full speed from an external supply if you adapt the plug. (PWM Adapter Cables)
