> 3 dayThese are as quite as they are ugly and they are really quite! None of the provided mounting hardware worked for my application so be aware you might have to hit the parts bin to make these work.

> 3 dayBought 2 for some extra cooling to the hard drive area of the Cooler Master HAF XB. I guess theyre working and quiet. Cant hear them over the battery backup in the same rack as the computer. Im glad the fans are on the inside of the machine and on the back of it because like every other Noctua fan, theyre ugly as sin. Came well-packaged and with multiple different connectors/extensions and mounting hardware.

24-12-2024I have a desktop mini fridge that had a 12v fan in it that was obnoxiously loud. So I swapped it with this one, which required splicing and soldering. This works great, its completely silent now, and still cools just as well. Love it!

> 3 dayIm using 2 of these fans in my front to pull cool air into the case and they are doing an excellent job keeping the airflow moving and the internal components (especially my GFX) cool. So far Im a new but HUGE fan of Noctua and believe they are the only company Ill be using for future cooling purchases. All of the recent fans (cpu cooler, 120mm, and 80mm) have been through Noctua for the efficiency of airflow and low noise they provided (none are using the provided low noise adapters as I havent seen the need to use them).

> 3 dayInstalled in an Icom IC-7300. It is much quieter than the stock OEM fan. Easy to install.

> 3 dayThe packaging screamed quality; adapter cables, extension cable, mounting screws, silicone mounting pegs, detailed instructions on the different uses and possible installation options, wrapped cables, etc... This fan comes with silicone anti-vibration mounts on all 8 corners that are removable, should you wish to. Quiet, this fan is whisper quiet, even at the highest speed. You can connect to 3 or 4 pin terminals on your motherboard. I could not be happier with this purchase & have already ordered a second fan.

Greater than one weekVery well made and includes several different cable lengths. Just doesnt plug into my DELL MB fan header. My oversight. I have had twp DELL PCs and know most DELL PCs use proprietary components. The thing that really torques my hind side is that the ONLY adaptor I have found to enable me to use the Noctua case fan costs as much as I paid for the fan. If I want to use the Noctua fan,I am going to have to find an adaptor, and I can tell you they are scarce. Bah Humbug DELL

> 3 dayQuert and cool. A bit pricey, but...yeah.
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.
