> 24 hourI bought two of these to put in my Thermaltake Suppressor F1 case to suck air out the back of the case. I only had one available 4-pin motherboard connector so I also bought the Noctua NA-SYC2 3-pin Y-Cable to daisy-chain them both off that connector.

> 24 hourI used this fan in my Tripp Lite rack mount UPS, since the fan in the unit runs 24x7. It did make the unit quieter, but not by much of a margin. Im thinking about doing something more complicated and measuring the heat on components directly, then enabling the fan until they cool down.

> 24 hourAbsolutely amazing fans for HTPC. Got 3 of these in Silverstone ML03B case and you will not hear them at all. Keeps my idle & in use temps nicely under control. Zero vibration noise, or really any kind of noise that you could hear when the computer is in use.

> 24 hourI replaced my 15 year old case fan with this fan. The old fan from the beginning was irritating to try to use the phone when the computer was running. I usually shut the computer off when using the phone. This fan is very quiet. I have two computers and I know my new one will have Noctua fans when I start hearing the case fans.

> 24 hourI hacked my studio light (godox SL-60w) and swapped the stock fan out with this fan, and it turned a previously noisy mess into a silent whisper. I cant even hear it unless Im in a dead quiet room and less than 1 foot away.

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 ULN version provides super-slow 1400/1100rpm speed settings for ultra-low-noise applications and highly noise sensitive users who demand 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.
