More info

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

Le NF-S12B : un concept qui a fait ses preuvesTens 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

La série redux : juste l'essentiel…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

Conçu pour une ventilation optimale des boîtiersTypical 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

Bevelled Blade Tips (Extrémité des pales biseautée)
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.


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.

Colour-customisable with NA-SAVP1 anti-vibration pads

Une customisation couleur grâce aux silentblocs NA-SAVP1The fan’s frame can be outfitted with Noctua’s chromax line NA-SAVP1 anti-vibration pads. Available in black, red, blue, white, green and yellow, these pads not only damp minute vibrations but also allow the fan to be colour-customised in order to coordinate it with popular build colour schemes!
