> 24 hourSilent Running. Got this fan for my old HP. Dropped right in. No problem. Used the reduced rpm cable included. Soooo quiet I catch myself grabbing my flashlight to see if its running....5 star !!

> 24 hourInstalled in an Icom IC-7300. It is much quieter than the stock OEM fan. Easy to install.

> 24 hourI am using other 120mm Noctura fans, and they are of good quality and run quietly forever. Quiet is the name of the game and Noctura does not disappoint. I purchased this 80mm fan based on past and present experience. I added it to my homebrew desktop computer specifically to cool a NVME Samsung 980 solid state C-drive (also purchased from Amazon). The ultra quiet Noctura fan knocked 20 degrees Celsius off the NVME. The fan comes with mounting gear, but I used plastic ties to position it for maximum cooling. This was installed at least 15 months ago, and all is still good. My rig only uses Noctura. Yes, highly recommend.

> 24 hourMy amp sounded like a Vacumm..now is super silent. Best mod ever to calm your noisy devices. I use them in my HTPC build as well.

> 24 hourAll the online review I read called this an excellent fan, and I must agree. It keep my case cooler than the old fan, is definitely quieter, and looks and feels like a quality product. It comes with a 4-pin connector, so my motherboard can control the speed (thats what PWM means). It generally runs at about medium speed (1800 rpm), but my making a special effort to load up my system, I can get it step up to 2200 rpm- and its still silent.
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.
