> 24 hourThe fan really is a premium fan. It really is quiet with rubber cushions. I will always use this as a upgrade from now on.

> 24 hourReplaced the large 120V fan in my Peavey 60/60 tube amp with this and stepped it down until it was quiet enough to record with.

> 24 hourNoctua produces quality fans. For most users go with the cheaper fans; they will usually work. From what I have noticed Noctua is more expensive because of their quality. Of course that is only my opinion.

> 24 hourI purchased the Noctua NF-A8 FLX 80mm fans to replace the stock fans in my Synology NAS box in order to achieve higher air-flow and quieter cooling for the always-on NAS box. I am a veteran computer builder and technophile, however this was my first experience with the Noctua fans. I was extremely impressed right out of the box.

> 24 hourBought one Noctua fan three years ago for a cpu cooler fan replacement. Now every fan in three systems is a Noctua fan. Nice and quiet. Accessories are great.

> 24 hourgreat silent fans. Got it to make my UNRAID Storage server a bit more quite. Before it sounds like a jet airplane. Now it just sounds like a car.
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 FLX version provides 2000/1650/1200rpm speed settings via the supplied Low-Noise Adaptors in order to provide full flexibility in fine-tuning the fan for maximum ventilation performance or 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.
