Description

Featuring advanced aerodynamic design measures such as flow acceleration channels and Noctua’s AAO frame, the NF-A6x25 is a highly optimized, quiet fan. It features a low-noise adapter to reduce the maximum speed during PWM control. Its advanced running smoothness, SSO2 bearing and Noctua’s trusted quality make it an elite choice for high demands.

  • Flow acceleration channels
  • Varying angular distance
  • AAO frame
  • Stepped inlet design
  • Inner surface microstructures
  • Integrated anti-vibration
  • SSO2 bearing
  • Custom designed PWM IC with SCD
  • Low-noise adapter

  • Flow acceleration channels
    The NF-A6x25 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.
  • Varying angular distance
    Thanks to its streamlined, compact motor design, the NF-A6x25's motor hub is small. This allows for more blade surface area and thus contributes to the NF-A6x25's superior airflow and pressure performance.
  • AAO frame
    Noctua's AAO frames feature integrated anti-vibration pads as well as Noctua's stepped inlet design and inner surface microstructures, both of which further refine the fan's performance and 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 plugging 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 silicone minimize the transmission of minute vibrations while maintaining full compatibility with mounting systems and fan clips used on heatsinks.
  • SSO2 bearing
    The NF-A6x25 features the further optimized 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-A6x25 PWM uses Noctua's custom designed NE-FD1 PWM IC that integrates Smooth Commutation Drive technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds.
  • Low-noise adapter
    The NF-A6x25 PWM is supplied with a low-noise adapter that reduces high fan speeds. It can be used either to run the fan at a fixed speed or to cap high speed when using automatic PWM control.
