• The NF-A8 is a highly optimised, premium quality quiet 80mm fan. Featuring Noctua’s AAO (Advanced Acoustic Optimisation) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A8 further improves the renowned quiet cooling performance of the award-winning NF-R8.
  • The ULN version provides super-slow 1400/1100rpm speed settings for ultra-low-noise applications and highly noise sensitive users who demand near-silent operation.
  • Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.


Succeeding the award-winning NF-R8
 Noctua's NF-R8 fan has become a default-choice among PC enthusiasts looking for a premium quality quiet 80mm fan.
 Thanks to its thoroughgoing aerodynamic optimisations, the NF-A8 provides higher static pressure and an even better airflow/noise ratio than its much acclaimed predecessor



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 Optimisation) 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 ploughing 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 pads
 Integrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.



Smooth Commutation Drive 2
 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-A8 remarkably quiet even at very close distances.
 2 speed settings for maximum quietness



SSO2 Bearing
 The NF-A8 features the further optimised 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 stabilisation, precision and durability.



2 speed settings for maximum quietness
  Providing 1400 and 1100 rpm speed settings via the supplied adapter, the ULN (Ultra-Low-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 minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary.
Both cables are fully sleeved.


6-year manufacturer’s warranty

6-year manufacturer’s warranty
 Noctua fans are renowned for their impeccable quality and outstanding longevity.
 Like all Noctua fans, the NF-A8 features an MTTF of more than 150.000 hours rating and comes with a full 6-year manufacturer’s warranty.
