Specifically designed for low impedance case cooling applications, the classic NF-S12B is a long-standing favourite among enthusiast users around the world and helped to found Noctua’s reputation as a top-tier manufacturer of premium quality quiet cooling components. The new redux edition reissues this award-winning model in a streamlined, accessibly priced package that has been reduced to the essential core: the NF-S12B premium fan. Its industry grade SSO-Bearing bearing, over 150.000 hours MTBF rating and full 6 years manufacturer’s warranty make the NF-S12B redux a proven premium choice that provides trusted Noctua quality at an attractive price point. The 1200rpm PWM version features Noctua’s proprietary NE-FD1 for automatic speed control, which allows to strike a perfect balance between high cooling capacity and low noise operation in each given situation.

Proven NF-S12B design Tens of thousands of quiet cooling enthusiasts around the globe swear by Noctua's classic NF-S12B. Thanks to its impressive quietness, excellent performance and impeccable quality, the NF-S12B has become an established reference for quiet 120mm fans.

Streamlined 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.

Designed for efficient case ventilation 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 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 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 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.

6-year manufacturer’s warranty Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the redux edition models feature an MTBF rating of more than 150.000 hours and come with a full 6-year manufacturer’s warranty.
