Description

The NF-A9 is a highly optimized, premium quality quiet 92mm fan. Featuring Noctua's AAO (Advanced Acoustic Optimization) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A9 further improves the renowned quiet cooling performance. The PWM version sports Noctua's custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a low-noise-adaptor to reduce the maximum speed during PWM control from 2000 to 1550rpm. Its superb running smoothness, reference-class SSO2 bearing and Noctua's trusted premium quality make it an elite choice for the highest demands.

  • Flow acceleration channels
  • AAO frame
  • Stepped Inlet design
  • Inner Surface Microstructures
  • Integrated anti-vibration
  • SSO2 bearing
  • Custom designed PWM IC with SCD
  • LNA low-noise adaptor

  • Flow acceleration channels
    The NF-A9 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.
  • AAO frame
    Noctua's AAO (Advanced Acoustic Optimization) frames feature integrated anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan's performance/noise efficiency.
  • Stepped Inlet design
    Noctua's Stepped Inlet design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space restricted environments.
  • Inner Surface Microstructures
    With the tips of the fan blades reaching through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.
  • Integrated anti-vibration
    Integrated anti-vibration pads made from extra-soft silicone minimize the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.
  • SSO2 bearing
    The NF-A9 features the further optimized second generation of Noctua's renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilization, precision and durability.
  • Custom designed PWM IC with SCD
    Supporting fully automatic PWM speed control, the NF-A9 PWM uses Noctua's novel, 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 low speeds.
  • LNA low-noise adaptor
    The NF-A9 PWM is supplied with a low-noise adaptor (L.N.A.) that reduces the maximum fan speed from 2000 to 1550rpm. The L.N.A can be used either to run the fan at a fixed speed of 1550rpm or to cap the maximum speed when using automatic PWM control.
