> 3 dayFans are very quiet. The only fan I have left to replace is the power supply fan. It is the loudest.

04-11-2024Put into a 3-year-old HP Pavilion 570 desktop that had a whirring fan noise at each startup. Then I had a warning on the screen to replace the fan. Got Amazon quick delivery, installed in 15 minutes, and - voila, the silence was deafening! Well packaged product, lots of accessory cables, very good quality item. Highly recommend.

> 3 dayExcellent fan!! Works flawlessly, although that was to be expected with noctuas quality. Fan is silent at low rpms, and not too loud when ramped up.

> 3 dayI 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 dayThis is a really great fan. Its hard to find a quality fan at 80mm. At this size, the fan either pumps a good amount of air but is loud, or is quiet, but ineffective.

> 3 dayReplaced 3 fans that come with the 2U rack mount case. Day and night different these fans are so quiet and keep everything cool.
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.
