> 3 daySilent, easy to install, great airflow, solid build quality. Great for HTPC

> 3 dayAn excellent fan, many cases have an extra 80mm mounting point or two, and this fan is perfect for squeezing some airflow onto a board that only has 2-3 fan headers, using the 3-pin end of a splitter (which I believe is included?), or with a 3-pin to MOLEX adapter (Which I dont think is included).

> 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.

> 3 dayI 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.

Greater than one weekI 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.

> 3 dayWould so recommend this if you have a PC with a LOUD 80mm fan. It moves a decent amount of air and is nearly inaudible.

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.
