> 3 dayUsed this to replace a noisy fan on a Behringer iNuke 3000. Fits perfect. Clip the plug off and use the red and black wires only. Cut the red/black wires for the stock fan and solder them to the red and black wires on the noctua. Your iNuke with be less than half as noisy.

07-06-2025Ordered 2 of these to swap out the loud fans in my mediasonic proboxs. I was able to make them fit with the existing back plate by ordering these screws with the fans. (https://www.amazon.com/dp/B01N3UXYJ6/ref=cm_cr_ryp_prd_ttl_sol_5). Now my enclosures are running with zero noise!

Greater than one weekBought this after trying cheaper alternatives which ended up being very noisy. When I first got this, I hooked it up to a power supply before I installed it just to see how quiet it was. At first I thought it wasnt running, but it was, and was just very quiet. Recommended!!

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 FLX version provides 2000/1650/1200rpm speed settings via the supplied Low-Noise Adaptors in order to provide full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. 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.
