> 24 hourBought 2 for some extra cooling to the hard drive area of the Cooler Master HAF XB. I guess theyre working and quiet. Cant hear them over the battery backup in the same rack as the computer. Im glad the fans are on the inside of the machine and on the back of it because like every other Noctua fan, theyre ugly as sin. Came well-packaged and with multiple different connectors/extensions and mounting hardware.

> 24 hourWorks great, very quiet. Many options for connecting. Utilized in a Behringer iNuke 3000dsp to quiet things down a bit.

> 24 hourI needed an 80mm case fan for a 2U rack mount case. 80mm fans tends to be loud, but this one was definitely quieter but still pumped the air needed to cool the components. Wherever I can, I buy Noctua fans. I dont care for the color, so I would prefer they not be fans used in visible spots, and they do have a grey/black version (Redux) but its less powerful. I would buy this fan again for case needs.

> 24 hourSuperior fan. Dead quiet. Everything is top notch. Cables are generous. adapters included.

> 24 hourDoesnt pull a ton of air, even at max speed, but its an 80mm fan. The rubber corners tend to slip and slide all over the place when installing them, but its a one-time inconvenience I can deal with.

> 24 hourReplaced stock fan in our nx300d amplifier with this fan. A bit of a passion to do but the sound reduction is pretty amazing. I suspect it also moves a bit less air but am very happy with the compromise
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.
