> 3 dayI have never had a Noctua fan fail, and some have been in service continuously for many, many years.

> 3 dayI purchased two of these to adapt a professional power amplifier to my home stereo environment. The amps original fans were aimed at high-output and durability, and unfortunately emitted an annoying bearing whine even at moderate speeds.

> 3 daythe headline explains my opinion. I use it in my ham radio equipment.

> 3 dayFor a long time, I used nothing but Panaflo fans. Most sleeve bearing fans, even some supposedly fancy ones, lockup after a year or two. Ball bearing fans *can* last longer (though some dont), but they tend to be noisy unless they are super-low RPM (I have a few Sunon fans that have been going for well over a decade). Panaflo fans are both quiet like a sleeve fan (because they are) and yet they seem to run forever. I have yet to have one fail even though some have been running continuously for a decade or more. However, the supply of those has pretty much dried up.

> 3 dayThey are ugly, and dont have fancy lights, but they are as quiet as a mouse fart, and work great

> 3 dayI 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.
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.
