> 24 hourits noctua, of course its going to be 5 stars but to be fair the rubber install thing is really hard to do.

> 24 hourI never knew fans could be this quiet. I bought 3 for my primary PC... installed them today and it almost sounds like the machine is not even turned on. I just ordered 3 more for my other PC.

> 24 hourLove this fan. Cant believe how quiet it is, but fan screws absolutely rip this thing up when you are screwing them in. Make sure you have compressed air around for when you are finished. Its actually super annoying so I had to subtract 2 stars. Im not a fan of the screwless mounts, so for me this was a big deal. If you like those things, then you will love this fan. Its operating much quieter and much more efficient than the 120mm Corsair stock (plastic, cheap, clear) fan on the back of my case.

> 24 hourBought 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.
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.
