> 3 daySecond to none for quiet and cool, but more expensive than most.. worth it for me but some may not agree.

> 3 dayGreat fan, replaced the stock 80mm that came on my CPU heatsink. Amazing difference in noise levels and moves plenty of air when the system asks it to. Everyone who is into PCs knows what Noctua fans are, and they are worth their price and their colors to have the best thermal performance for your PC.

Greater than one weekSimply amazing airflow. Moves a ton of air and really keeps the important parts cool. Using as exhaust fans in an enclosed mining rig.

> 3 dayFit perfectly in an older Dell 790 SFF. Less noisy than the stock fan. Seems to be keeping things cool. Had to use with a Pocaton 5Pin Female to 4Pin Male Socket Connector Jack PWM Cooling Fan Power Cable Compatible with DELL PC in order to connect to the motherboard.

> 3 dayIm disappointed with this fan. Its super loud. I installed it in my Dell Optiplex and its louder than my stock CPU fan, Case Fan and 120mm front case fan altogether!

> 3 dayI have a Corsair Air 240 case which had an EVGA GTX 770 2 GB ACX GPU in, which kicked out quite a bit of warm air into the case. I already had two 120mm top-mounted fans pulling air up and out the top of the case, but I wanted to get some back-mounted exhaust fans as well to pull out additional heat. Since the Air 240 is limited to 80mm back exhaust fans, these Noctua NF-A8 fans provided exactly what I needed. I used the ASUS Q-Fan control to tune the fans, and these bad boys help keep the case whisper quiet while still turning up the RPMs when detecting heat exceeding preset thresholds. Im not a huge fan of the color scheme (since nearly everything else in my case is either black or silver/white), but its not enough to knock any stars off the product itself.

Greater than one weekThis is my review of the Noctua NF-A8 PWM quiet fan 80mm brown.
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.
