Noctua NF-A8 ULN - Case fan - 80 mm | NF-A8 ULN

Product Features

• Flow Acceleration Channels
  The NF-A8 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.
• Innner Surface Microstructures
  With the tips of the fan blades plowing 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.
• Smooth Commutation Drive 2
  Noctua's advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the NF-A8 remarkably quiet even at very close distance.
• SSO2 Bearing
  The NF-A8 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.
• 2 speed settings for maximum quietness
  Providing 1400 and 1100 rpm speed settings via the supplied adapter, the ULN (UltraLow-Noise) version is tailor made for serious silent enthusiasts who demand super-slow running speeds and utmost quietness of operation.
• Extensive cabling options
  The fan's short 20cm primary cable minimizes cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and the supplied 3:4 pin adaptor allows to connect the fan directly to the power supply.
