Features:

  • Flow Acceleration Channels Reduced Motor Hub Size
  • Integrated Anti Vibration Pads Smooth Commutation Drive 2 SSO2 Bearing
  • Low Noise Adaptor for full flexibility
  • 3 to 2 pin Adaptor and Polarity Protection
  • Extensive cabling options 6 year manufacturer s warranty
  • Voltage 12 V
  • The NF A4x10 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.
  • Thanks to its streamlined, compact motor design, the NF A4x10 s motor hub is smaller than with conventional 4cm fans. This allows for more blade surface area and thus contributes to the NF A4x10 s superior airflow and pressure performance.
  • 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.
  • 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.
  • With the tips of the fan blades ploughing thru boundary layer created by Inner Surface Microstructures, flow separation from suction side of the blades is significantly suppressed, which reduced blade passing noise, improved airflow, pressure efficiency.
  • Integrated Anti Vibration Pads made from extra soft silicone minimize the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heat sinks.
  • The latest version of Noctua s advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the NF A4x10 remarkably quiet even at very close distance.
  • The NF A4x10 is supplied with a Low Noise Adaptor L.N.A. that reduces the maximum fan speed from 4500 to 3700rpm so that it can be fine tuned for superior airflow or maximum quietness.
  • Premium quiet fan, 40x40x10 mm, 12V, 3 pin Molex, 4500 3700 RPM, max. 17.9 dB A , 150,000 h MTTF
  • Award winning 40x10mm A series fan with Flow Acceleration Channels and Advanced Acoustic Optimisation frame for superior quiet cooling performance
  • Ideal replacement for noisy or broken 12V 4cm fans in 3D printers, DVRs, NAS, switches, routers, other network and storage devices, etc.
  • 3 pin 12V FLX version can be run 4500 or 3700 rpm using the supplied Low Noise Adaptors to fine tune the fan for maximum airflow or near silent operation
  • Includes anti vibration mounts, fan screws, Low Noise Adaptor, extension cable and OmniJoin adaptor set for connecting the fan to proprietary fan headers
