PC Fan - size: 120 × 25mm, 300 RPM - 1300 RPM, 12 V, maximum noise level of up to 19,8 dB, 4pin PWM, PWM 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...
