The NOCTUA NF-P12 PWM fan is among the award-winning models that brought the brand NOCTUA into the limelight. It uses the power of nine integrated blades with a diameter of 120mm. The speed of the blades reaches up to 1300rpm. Airflow is increased due to the cuts on the tips of the blades. Supporting fully automatic PWM speed control, the fan uses Noctua's 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 low speeds. It also offers an unprecedented average lifespan exceeding 150,000 hours (17 years!).
Pressure-optimised Nine-Blade Design + Vortex-Control Notches
Specifically developed for high-impedance applications such as CPU coolers, water-cooling radiators or cases with tight fan grills, the NF-P12 PWM provides outstanding pressure and airflow performance. 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-P12 PWM sound more pleasant to the human ear.
Custom-designed PWM IC with SCD
Supporting fully automatic PWM speed control, the fan uses Noctua's 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 low speeds. The NF-P12 PWM is supplied with a (L.N.A.) that reduces the maximum fan speed from 1300 to 900rpm. The L.N.A. can be used either to run the fan at a fixed speed of 900rpm or to cap the maximum speed when using automatic PWM control.
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 the connection of a second NF-P12 fan to the same PWM fan header for automatic control.
Combining the proven concept of hydrodynamic bearing with an additional magnet that supports the self-stabilisation of the rotor axis, Noctua's time-tested technology has become synonymous with supremely quiet operation and exceptional long-term stability.
