> 3 dayNoctua fans always worth it. Take any case and make it a quiet case. Take a quiet case and make it silent. Packaging is fancy, but comes with everything youll ever need. A bit wasteful in that regard, but useful if you havent planned your build out to a T.

Greater than one weekNice and quiet. I had a loud subwoofer amp with an 80mm fan and I fixed it with this fan. It provides enough CFM but is super quiet,

> 3 dayThe fan on my Marantz MM7055 Amp was running loud, probably bad bearing or dust collected on the blades caused it to be noisy which ruins a good audio experience during a movie. Swapped the Marantz amp out with these, with little wire solder and now the amp is extremely quiet.

> 3 dayI purchased a brand new high current switching power supply. The cooling fan was extremely loud and was totally annoying to be in the room with it. I purchased this Noctua NF-A8 to replace it and was totally satisfied. The Noctua also delivered the same amount of cubic feet of cooling as the OEM one but was barely noticeable audibly.

> 3 dayI am impressed with this product. Build quality is excellent, the accessories are useful, and instillation was a breeze. I can’t speak to unique measurements, but the fans moves a ton of air and is quieter than other rigs w/ same size fans. I’d highly recommend.

> 3 dayMy last 8$ 80 mm fan never worked right out of the box so fortunately that led me to step up to a Noctua. Great air movement and very quiet. Im using two of them to cool my 2.8 kw Outback inverter, which has a very loud internal cooling fan. I havent heard the inverter fan since, even under heavy loads. These Noctuas really keep thing cool. Ive seen a couple reviewers say theyre not quiet, I think these folks have got a screw loose somewhere. Beautiful packaging, info and accessories, RPM adaptors, extension cable, etc..

03-06-2025these noctuc fans are premium-however they run so slow they just do not supply enough air volume for CPU cooling !

Greater than one weekNo issues used it to replace a fan on my pop can refrigerator.
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 FLX version provides 2000/1650/1200rpm speed settings via the supplied Low-Noise Adaptors in order to provide full flexibility in fine-tuning the fan for maximum ventilation performance or 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 ChannelsThe 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 bearingThe 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 padsIntegrated 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. |
Scope of delivery
|
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.
