NF-B9 Redux-1600 PWM

The classic NF-B9 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-B9 premium fan. Its industry grade SSO-Bearing, over 150.000 hours MTBF rating and full 6 years manufacturer’s warranty make the NF-B9 redux a proven premium choice that provides trusted Noctua quality at an attractive price point. The 1600rpm PWM version features Noctua’s proprietary NE-FD1 PWM IC 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-B9 design
  Tens of thousands of quiet cooling enthusiasts around the globe swear by Noctua’s classic NF-B9. Thanks to its impressive quietness, excellent performance and impeccable quality, the NF-B9 has become an established reference for quiet 92mm 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.
• Vortex-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 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.
