Noctua NF-A8 ULN Fan - 80mm

Noctua is a well-known name in the silent cooling market, with the Austrian manufacturer's CPU coolers enjoying an excellent reputation. They combine outstanding build quality with high cooling performance and minimal noise levels. This is largely thanks to Noctua's proprietary fans, which are also sold separately for use as case or CPU fans.

The NF-A8 is a quiet 80 mm premium fan with a square AAO (Advanced Acoustic Optimisation) frame. Its square shape and 80 mm mounting holes make it an excellent choice for use as a case fan. With advanced aerodynamic design measures like Flow Acceleration Channels, the NF-A8 offers improved silent cooling performance compared to the highly acclaimed NF-R8.

The ULN version offers ultra-low speed options (1,400/1,100 RPM) for near-silent operation, making it perfect for ultra-low noise applications and noise-sensitive users. Its superb smoothness, reference-class SSO2 bearing, and Noctua's proven premium quality make the NF-A8 ULN a top-tier solution for the most demanding requirements.

Noctua’s NF-R8 has become a standard solution for PC enthusiasts seeking premium-quality 80 mm fans. With extensive aerodynamic optimisations, the NF-A8 achieves higher static pressure and an improved airflow-to-noise ratio compared to its renowned predecessor.

With its square frame and 80 mm mounting holes (124.5 mm hole spacing), the NF-A8 is an ideal premium upgrade for standard 80 mm case fans. It is also perfect for use on 80 mm water cooling radiators, where the square shape ensures full coverage of the cooling fins and optimal pressure performance.

The NF-A8’s impeller features Flow Acceleration Channels on the suction side. By accelerating airflow in critical outer regions of the fan blades, suction-side vortex shedding is reduced, leading to greater efficiency and lower turbulence-induced noise emissions.

Noctua's AAO (Advanced Acoustic Optimisation) frames are equipped with integrated vibration pads, a stepped inlet design, and inner surface microstructures, which further enhance performance-to-noise efficiency.

Anti-vibration pads made of extra-soft silicone reduce the transmission of even the smallest vibrations and are compatible with all standard screws, common mounting systems, and fan clips used with CPU coolers.

Despite its improved performance, the NF-A8 ULN’s power consumption is just 0.6 W, making the fan not only environmentally friendly but also a great way to lower your electricity bill!

Noctua fans are renowned for their flawless quality and exceptional longevity. Like all Noctua fans, the NF-A8 has an MTBF (mean time between failures) rating of over 150,000 hours and comes with a full 6-year manufacturer’s warranty.
