    Worked for RV refrigerator to circulate air to help keep temps even and cool faster. Very quiet.

    This thing is as quiet as a fan that is off. And, it also moves air exactly as well as a fan that is off.

    I never knew fans could be this quiet. I bought 3 for my primary PC... installed them today and it almost sounds like the machine is not even turned on. I just ordered 3 more for my other PC.

    I bought Two of these for my new build. I purchased these ULN fans when i should have bought PWM. My mistake! I had them installed and both were working fine, however, within two weeks, one began to show signs of failure. Two days later, it failed. I returned it and ordered two of the PWM fans instead.

    Must have quality/reliability. We use these in nearly all our desktop computers as well as in the servers.

    Great product. Runs super quiet and moves a lot of air.

    I have never had a Noctua fan fail, and some have been in service continuously for many, many years.

    Extremely quiet fans that came with a load of power connectors.

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.

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.

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.

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.

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.

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.
