Product Description

Noctua NF-B9 PWM 92x92x25mm PWM Bevelled Blade Tips with Vortex-Control Notches SSO Bearing Fan

Beveled blade tips reduce critical rotor/ stator interaction, combine a higher blade surface area with quieter operation and form a cornerstone of the fan's efficiency.
Vortex-control notches split up trailing edge vortices and spread the fan's noise emission over a wider range of frequencies.
Supporting fully automatic speed control, the NF-B9 uses Noctua's novel, custom-designed NE-FD1 IC that integrates Smooth Commutation Drive (SCD) technology.
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 run the fan at a fixed speed of 1300rpm or cap the maximum speed when using automatic control.

The classic NF-B9 92mm fan helped to found Noctuaâ‚¬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 Noctuaâ‚¬s novel, custom designed PWM IC for fully automatic control and ultra-low power consumption. Equipped with Noctuaâ‚¬s signature SSO bearing and topped off with a 6 years manufacturerâ‚¬s warranty, the NF-B9 PWM is a proven premium choice for the highest demands.
