> 3 dayAll the online review I read called this an excellent fan, and I must agree. It keep my case cooler than the old fan, is definitely quieter, and looks and feels like a quality product. It comes with a 4-pin connector, so my motherboard can control the speed (thats what PWM means). It generally runs at about medium speed (1800 rpm), but my making a special effort to load up my system, I can get it step up to 2200 rpm- and its still silent.

> 3 dayIll keep it short: my computers stock fan was so loud, it was making the whole pc tower vibrate and caused a massive amount of noise. I can still remember the vibrations from my legs and arms making contact with the desk. I finally got tired of it and ordered this fan. It took about a minute to install and turn it on and that was that. No more noise. Its like its not even on. If I hadnt seen the blades spinning, Id think I got a dud. It also keeps the PCs temperatures far lower than the stock fan. All I can say is that Ill never go back to regular fans. Its that good.

> 3 dayUsed this in my NAS and PC build. Theyre quiet and move a decent amount of air. My complaint is the color. Brown?! Really. And price is a little high. worth it, that would be a personal choice.

Greater than one weekGreat fan real quite beats the stock fans engine turbines and its not even running hot and so loud. Glad I bought this I can enjoy my streaming.

Greater than one weekAs 70s/80s as they look with the sexy brown and beige color scheme, these puppies are incredibly high quality, incredibly silent, and move some air. Highly recommended. The rubber bits at the corner to help dampen any vibrations are a thoughtful touch.

> 3 dayWorth every penny, if you want a quiet PC Noctua is the only way to go

> 3 dayThe compactness and power is good and the price is fair but maybe a little inflated. Ive heard their regional quality can be wanting too so I hope noctua does a better job with that. This fan, however, is pretty quiet as I dont have it in a 4 pin slot.
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.
