> 24 hourThe packaging screamed quality; adapter cables, extension cable, mounting screws, silicone mounting pegs, detailed instructions on the different uses and possible installation options, wrapped cables, etc... This fan comes with silicone anti-vibration mounts on all 8 corners that are removable, should you wish to. Quiet, this fan is whisper quiet, even at the highest speed. You can connect to 3 or 4 pin terminals on your motherboard. I could not be happier with this purchase & have already ordered a second fan.

> 24 hourRelatively quiet and moves a decent about of air. Workmanship is top notch. Just love the Noctua fans.

> 24 hourThese things are expensive, but I think they are worth the price. They push a large amount of air, and are the quietest fan I have ever seen. Also, Noctua stands behind their products. A friend of mine had an issue with his, and they quickly replaced it.

> 24 hourI bought a 92mm and 80mm Noctua case fan and so far it really made a difference in terms of noise reduction. I switch Noctua fan with my old one and i thought my PC died on start up because of the sudden drop of noise after 1-2 second of starting up. I can actually hear what is happening inside my PC now due to the fan being almost dead silent.

> 24 hourThis review is for both the 92mm and 80mm versions of this model, 4-wire units with speed controlled by the motherboard.

> 24 hourReplaced 3 fans that come with the 2U rack mount case. Day and night different these fans are so quiet and keep everything cool.

> 24 hourIf you are into fancy boxes and flashy marketing then buy this. This is just got a little bit more flare with the rubber attachments and louder than the NF-R8 (NF-R8 rated at 17.1). If you stick the adapter (but why bother? ) you can get the sound down a little bit more for the price.

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.
