The Noctua NF-S12B redux is a premium quality quiet 120mm fan at an attractive price point, specially designed for low impedance case cooling applications. It has a sophisticated design, and features 1200rpm spinning speed, and Bevelled Blade Tips, providing superior airflow. It sports Noctua’s exclusive NE-FD1 PWM IC for automatic speed control, allowing to strike a perfect balance between high cooling capacity and low noise operation in each given situation. Plus, the industry-grade SSO bearing guarantees an MTBF of over 150.000hrs.

Designed for Efficient Case Ventilation

General information

Typical PC case ventilation applications require high airflow but only medium static pressure. The NF-S12B has been specifically designed for high airflow efficiency and low noise in order to provide best results in these so called low impedance applications


Bevelled Blade Tips

General information

Reducing critical rotor stator interaction, Bevelled 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.


Custom Designed PWM IC with SCD

General information

Supporting fully automatic speed control via PWM, 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 lower speeds.


SSO Bearing

General information

Combining the proven concept of hydrodynamic bearings with an additional magnet that supports the self-stabilization of the rotor axis, Noctua’s time-tested SSO-Bearing technology has become synonymous with supremely quiet operation and exceptional long-term stability.


Optional Accessories

General information

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.
