> 24 hourPurchased 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.

> 24 hourA good replacement of OEM fans, if you want non-vibrating and quiet 80mm fan. The only con is the color palette, but, as its sort of Noctuas signature, theres nothing you can do about it.

> 24 hourI replaced the stock fan on my ICOM IC-7300 transceiver and it is much quieter. The unit moves more than enough air to keep my rig cool during long transmissions at full power. Exact details for making the change-out are available on the web.

> 24 hourVery 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.)

> 24 hourI bought this to replace the original fan in my Xaminer 64tb - This is the only approved replacement fan for Xaminer (as of 9/8/22). The original got progressively noisier over a period of several months until it failed completely.

> 24 hourUsed these fans to replace the factory fans in my Inuke 6000dsp amp. These fans are so much more quieter.

> 24 hourrigged this to an old GTS 290 whose fan died. used somewhat heavy duty thread to tie it to the heatsink. It was easy to remove the plastic protector from the fan plug on the board and plug this one in. works well and I have better temps that before (basic daily usage), even after cleaning while still using the old fan.

> 24 hourInstalled this under the Swiftech MCP 35x2 heatsink and it works great. Theres not much clearance at all, but it does a beautiful job at cooling the pumps. PWM is a plus, and very 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.
