Typical PC case ventilation applications require high airflow but only medium static pressure. NF-S12B has been specifically designed for high airflow efficiency & low noise in order to provide best results in these so called low impedance applications.
Reducing critical rotor stator interaction, Beveled Blade Tips permit to combine extended leading edges and a higher blade surface area with quieter operation and thus form a cornerstone of the fan’s outstanding efficiency.
Supporting fully auto. speed control via PWM, the fan uses Noctua’s custom designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) tech. SCD suppresses PWM switching noises & thus makes the fan quiet at lower speeds.
Combining the proven concept of hydrodynamic bearings with an add’l magnet that supports the self-stabilization of the rotor axis, Noctua’s time-tested SSO-Bearing tech has become synonymous with supremely quiet operation & exceptional long-term stability.
Users can choose from Noctua’s wide range of optional accessories such as anti-vibration mounts, Low-Noise-Adaptors, y-cables, 3:4 pin adaptors or extension cables to upgrade redux edition fans according to their individual needs.
