Greater than one weekThis thing is great, moves air well, and is far quieter than previous cooling fans. I cant say it is as quiet as the previous reviews made it sound, but my girlfriend is much happier with the noise from my CPU case now -- it used to drive her bonkers! :-)

Greater than one weekExcellent replacement for an OEM fan on IC-7300. Almost noiseless. Took a little work (see various websites), but worth the $, work, and time.

> 3 dayThis is a really nice fan, super quiet. The price for this fan is a little bit more than most but a really good value for such quality.

> 3 dayEssential component to a recent ITX build of mine (Fractal Ridge). You get what you pay for with Noctua - in this case, that means okay/good CFM at lower speeds while also yielding extremely quiet noise levels.

Greater than one weekThis 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 dayI 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.

Greater than one weekNot loud at all. Barely even hear it.
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.
