> 3 dayI have never had a Noctua fan fail, and some have been in service continuously for many, many years.

> 3 dayAbsolutely amazing fans for HTPC. Got 3 of these in Silverstone ML03B case and you will not hear them at all. Keeps my idle & in use temps nicely under control. Zero vibration noise, or really any kind of noise that you could hear when the computer is in use.

> 3 dayThese fans exceed expectations. I purchased them to make my home file server quieter. They are nearly silent and push a ton of air. Will buy again in the future.

Highly Recommend
Greater than one weekJoin the Cult of Noctua, we welcome all willing to invest. Even the tiny ones barely make any noise.

> 3 dayThis thing is as quiet as a fan that is off. And, it also moves air exactly as well as a fan that is off.

> 3 dayLove this fan. Cant believe how quiet it is, but fan screws absolutely rip this thing up when you are screwing them in. Make sure you have compressed air around for when you are finished. Its actually super annoying so I had to subtract 2 stars. Im not a fan of the screwless mounts, so for me this was a big deal. If you like those things, then you will love this fan. Its operating much quieter and much more efficient than the 120mm Corsair stock (plastic, cheap, clear) fan on the back of my case.

> 3 daythe headline explains my opinion. I use it in my ham radio equipment.
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 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.
