> 24 hourOne of the best fan I have purchased. Its so silent that I need to look at the blade or feel the airflow to confirm f the blades are turning.

> 24 hourAfter installing Noctua fans in my system is dead silent. The Seagate 2tb HDD is nearly as loud as these fans. Dead silent! I would recommend to anyone whos interested just for the quietness factor as I was.

> 24 hourI 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.

> 24 hourI 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.

> 24 hourHad originally purchased an Arctic 80mm fan that was DOA. Returned it to Amazon and researched for a better one. Voila! The noctura is excellent. Definitely a better quality fan than the Arctic. It came with a variety of power connectors/adapters to enable power and speed options and 3 or 4 pin connection to your PC.

> 24 hourLove these guys, super quiet, ended up not being fast enough those for most 80mm application. Usually when I come across a 80mm its ether got to force air through a whole case (like in a server a NAS setting) or its used in the basement of a case (big area of empty space) this works better for the later because it will evacuate the hot air to a point, but its not going to do much to cool any components in there, more just like maintain the status quo. Thats to be expect though with a 80mm 2500 rpm fan. I will say it is so damn quiet at 2500 rpms. I use them in my gaming case to keep the harddrives from getting too hot. But its not fast enough for my nas build to cool off 8 drives. For that you need something that can force more air like 4000-5000rpm.

> 24 hourA little thicker than I was expecting but thats my fault for not checking the dimensions. Amazing fans, push a lot of air and stay quiet at full speed. Even more quiet than my 140mm CoolerMaster fans.
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.
