> 3 dayI bought a Dell 3880 and its a great little system... EXCEPT THE CPU FAN IS TOO NOISY. If youre in a quiet environment then you will almost certainly notice the noise.

> 3 dayThese fans are much quieter than stock fans and provide good air flow as well.

> 3 daySuperior fan. Dead quiet. Everything is top notch. Cables are generous. adapters included.

> 3 dayPurchased two of these fans for use in a Silverstone GD09B HTPC chassis. Was worried that running two 80mm fans in here 1) wouldnt fit, and 2) would be too loud. Am happy to report that these fit side by side easily in the rear exhaust area on the Silverstone case, and that they are not audible using the standard profile from my motherboards pwm header.

> 3 daySimply amazing airflow. Moves a ton of air and really keeps the important parts cool. Using as exhaust fans in an enclosed mining rig.

> 3 daythese fans are more quiet than the hard drives, I now need to figure out how to configure spindown on the drives on linux.

> 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.

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.
