Greater than one weekI have used many Noctua Fans over the years. vv I have had a a number in service (80mm and 120mm) ~ 10 years 24/7/365 with NO failures.

> 3 dayBought 5 of these for Home server, can’t even tell it’s on with how silent it is.

> 3 dayIts a Noctua fan. The name (and color) speaks for itself. Quiet, efficient, and gets the job done. Enough said!

> 3 dayThis was easy to install and i am an 65 year old with arthritic hands! They had different hardware depending on your need. Works great and not noisy. My desk top cabinet is right next to my recliner. I never hear it.

Into the Details
14-06-2025I bought this to replace the original fan in my Xaminer 64tb - This is the only approved replacement fan for Xaminer (as of 9/8/22). The original got progressively noisier over a period of several months until it failed completely.

> 3 dayNoctua fans are no joke. Fans quieter @ 2200rpm than some 140mm @1300rpm.

Greater than one weekInstalled in an Icom IC-7300. It is much quieter than the stock OEM fan. Easy to install.

> 3 dayFeels well made, delivers on how quiet it is. Could probably cost half as much if the extra 3 cables I dont need and fancy packaging were optional.
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 PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 2200 to 1750rpm. 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.
