> 3 dayIm using it as a OEM fan replacement on top of the OEM Intel heatsink for a i7-7700 CPU. It made a 5 to 8 degree Farenheit difference. Thats better than nothing. Before anyone says, just replace the stock heatsink with an aftermarket upgrade you big dork!, LOL..., I tried that already.

28-09-2024If you have to install two of these packed together all the rubber noise reduction will make this tricky. I had to put the screws on and angle to get the second fan in my case.

> 3 dayReplaced 3 fans that come with the 2U rack mount case. Day and night different these fans are so quiet and keep everything cool.

> 3 dayPleantly surprise to see a conservative spec on noise reduction. The Noctura fan was better than its published spec.

> 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 dayGreat 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.
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.
