> 3 dayThis fan is amazing. I needed a small fan to fit in a side panel of my silverstone sg13 and originally had a be quiet pure wings in there. The be quiet fan made a horrible whining noise that drove me nuts. I put this notuca fan in (with the noise reduction cable that comes with it because it is running on a fan splitter) and it is dead silent. If you need quiet, this is the fan to get.

> 3 dayQuiet and powerful. A little too thick to replace the 80mm fan in my Cooler Master 130 Elite unless I take out the metal plate and just leave it without securing with the screws provided. However it is thick enough that theres no need for that at all.

> 3 dayVery quiet, but still moves a reasonable amount of air. Great choice for mini-ITC case builds. Strange color, if youre sensitive to color in your PC builds. A new model is available in black. Very high recommendation.

Greater than one weekWow. What a difference. I replaced a Silenx Ixtrema Pro IXP-54-14 that had seized up. The packaging reminds me of a Nest or iPhone. Build quality seems to be very good, the power cable was a little short but an extension cable is included (along with a 3 to 4 pin adapter and a low-noise cable that makes the fan spin slower). Took five minutes to swap out the fans and it is very silent. Better quality than I expected. A pleasant surprise.

02-06-2025I 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.

> 3 dayI was hoping for better air flow, but thats my own fault for overestimating the specs. Build wise the drive is very solid, still, and extremely quiet. Great fan.. Cant really attest to its supposed better static pressure as it doesnt put out much air flow. Works great for what it is, i just need more.

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.
