15-11-2024Bought this to replace a noisy fan in my switching power supply, installed without a hitch and works great. Best of all....its quiet. Hard to talk on my amateur radio with a noisy fan in the background. I had bought one for a replacement on one of my radios a few months earlier and couldnt be more satisified.

15-11-2024Spent over 100 dollars in Noctua fans already. I put that stuff on everything... Simply the best, just buy them. They are an ugly shade of brown? When you plug them in you will understand and completely ignore this fact, I guarantee it.

> 3 dayGreat upgrade for the old fans in my PC case. Noise level cut by 90% as compared to a molecule fan from 2003. I know that’s not much to go off of but it changed my PC so much for the better, no reason not to go noctua every time.

> 3 dayExpensive but worth it. Used these to replace rosewill fans in a media server case that sounded like a vacuum. So much quieter.

Greater than one weekits so quiet its shocking not to hear any fan case noise when the PC is on, I thought it wasnt running but looked at the fans with a flashlight, and they spin, but are silent, good quality, really improves PC time with a quiet background

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.
