Noctua NF-A8 ULN 80mm Ultra Quiet Computer Fan
Noctua NF-A8 ULN 80mm Fan
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
Noctua NF-A8 ULN Features
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.
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 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.
Noctua 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.
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.
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 distance..
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 and a 4-pin y-cable allows to connect a second NF-A8 fan to the same PWM fan header for automatic control.
6 years Manufacturer’s Warranty
Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A8 features an MTBF rating of more than 150.000
hours and comes with a full 6 years manufacturer’s warranty.
