Streamlined redux editionStreamlined redux edition
The redux product line reissues some of Noctua's most popular, award-winning models by presenting them in streamlined, accessibly priced packages. All redux edition products are industry proven, time-tested models that helped to found Noctua's reputation as a first-tier supplier of premium grade low noise cooling equipment.
Vortex-Control NotchesVortex-Control Notches
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 fan sound more pleasant to the human ear.
Bevelled Blade TipsBevelled Blade Tips
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 SCDCustom-designed PWM IC with SCD
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-BearingSSO-Bearing
Combining the proven concept of hydrodynamic bearings with an additional magnet that supports the self-stabilisation 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
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.

NOTE: PWM Fans are not variable speed control fans on their own. An integrated circuit varies the speed and airflow of a fan using a pulse-width-modulated (PWM) voltage in response to temperature or system commands send typically by a computer motherboard. You can use them to run at full speed from an external supply if you adapt the plug. (PWM Adapter Cables)
