> 3 dayThese are the best fans in the world for a reason... and even though they are the most hideous PC parts that Ive ever seen, I dont think that Ill ever go back.

> 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 dayTheyre very much adaptable to different cases. Super quiet. The evidence I needed that you get what you pay for, and Noctua means truly high quality

> 3 dayGot this as an upgrade for my Evercool 5.25 drive bay. Moves more air at lower db with and is a better quality build overall. Hard to beat Noctua.

> 3 dayVery low noise fans. The quiet adapter it comes with is really good. I have 5 nested 4 pin PWM fans plugged into the little low noise adapter cable. now all fans are running at 600~ rpm (what i needed). Now I can sleep at night without turning off my server. (This could have been done through BIOS or a fan controller. But, it is still very neat.)

Greater than one weekA bit more expensive than most fans of the same size, but they are rather quiet and will move air effectively. I have a pair in the back of a rack-mount computer case and it does the job well, quietly.

> 3 dayReplaced a noisy Cooler Master fan that came with my HP computer with this one. What do I hear now? Absolutely nothing.

> 3 dayMost 80mm fans are noisy, these, like other fans from Noctua, these are whisper quiet.
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.
