13-11-2024This is the quietest fan Ive ever used - dead silent, in fact; however, the reason its so quiet is that it doesnt spin. When the computer starts, the fan spins for less than a second then does nothing, no matter how warm the computer gets. Ive tried several other fans on the same MB header, all work. The other fans are noisier than Id like, which is why I ordered this one. If, however, the tradeoff for a quieter computer is overheating, Ill endure the noise.

Greater than one weekExcellent fan!! Works flawlessly, although that was to be expected with noctuas quality. Fan is silent at low rpms, and not too loud when ramped up.

> 3 dayI purchased these to replace some stock fans. They’re super quite and are easy to install. These are by far my fan of choice

Greater than one weekHave this in an older Antec case Thats has space for 1 120mm fan and 1 80mm fan. The stuck 80mm was very loud and had some funky LEDs. Replaced it with one of these and added a second to the 5.25 inch bays. Super quiet and moves a good amount of air. Little bit pricy but not too bad

> 3 dayI forgot I had these. Seriously... They were so quiet I forgot I bought these/they existed at all. It moves a ton of air and couldnt be happier! :D

Greater than one weekMy computer chassis came with a very cheap and loud three pin fan. When I built the computer I decided to upgrade it and what a difference. This thing is super quiet and since it is a 4 pin I have more control over its function in the BIOS. Color isnt a problem for me since I cant see it on the back of the computer. Great upgrade for me. I also have the Noctua Low-Profile Quiet CPU Cooler for Intel 115x Based Retail Cooling NH-L9I and they go together well. Love this brand!
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.
