Greater than one weekWould so recommend this if you have a PC with a LOUD 80mm fan. It moves a decent amount of air and is nearly inaudible.

> 3 dayBought to replace the stock fan in my Fractal AxeFX II XL, they are notoriously loud. I had to get new screws due to this fan being more than twice as thick, however it fits great and is MUCH quieter and well designed as compared to the stock fan. The included cables are nice as well, would definitely buy again.

Greater than one weekWorks, moves air, quiet. Will update as time passes. Installed on 2/14/2022 will see the life of it.

> 3 dayThis is the best fan you can buy. I have one of these and 3 120mm Noctuas, and they are well made, come with many useful accessories (adapter cables, silencer cables, extension cables, extra grommets) and are nearly silent when properly controlled by software or using the silencer cable (which reduced the fans RPM). Well worth the extra money, especially for a living room system that is powered on 24x7 and needs reliability and low noise.

> 3 dayLook, these fans are not inexpensive, but they are worth buying if fan noise must be minimal to nonexistent.

Greater than one weekYes they are expensive, but will give you years of great service, very quiet as well

> 3 dayFor a long time, I used nothing but Panaflo fans. Most sleeve bearing fans, even some supposedly fancy ones, lockup after a year or two. Ball bearing fans *can* last longer (though some dont), but they tend to be noisy unless they are super-low RPM (I have a few Sunon fans that have been going for well over a decade). Panaflo fans are both quiet like a sleeve fan (because they are) and yet they seem to run forever. I have yet to have one fail even though some have been running continuously for a decade or more. However, the supply of those has pretty much dried up.
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 ULN version provides super-slow 1400/1100rpm speed settings for ultra-low-noise applications and highly noise sensitive users who demand near-silent operation. 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.
