Greater than one weekIve used these for decades and they simply work, every time, in silence.

Greater than one weekVery quiet fans. Bought two of these to just to provide a little circulation in the bottom chamber of my Cooler Master HAF XB EVO (yeah...probably overkill since most of the heat generating components are in the upper chamber....but figured what the heck since I was populating the other fans with Noctuas). Anyway, when I first powered the system on I had to visually inspect the fans to make sure they were spinning because they were so quiet. How cool is that... (horrible pun)

I buy too much
> 3 dayThese fans may not be the cheapest, but they are extremely quiet and have a reputation for reliability. Comes with an array of cables and some rubber mounting pegs.

Greater than one weekI hoped this fan would be a little more quiet. I have previously modified a regular 80mm case fan with a resistor and feel like they provide about the same RPM and noise level. In the end, I kept this one in place, as the case this guy is sitting in is pretty tight and quite painful to operate on.

> 3 dayI put these in the back wall of a 4U Supermicro 846 chassis and they are quieter at full tilt than the stock fans ramped down. To make up for the lack of air flow I have three 140mm Noctua industrial fans installed on the front. I can now sit three feet away and not need ear plugs. These fans are known as the best for a reason.

> 3 dayInstalled this under the Swiftech MCP 35x2 heatsink and it works great. Theres not much clearance at all, but it does a beautiful job at cooling the pumps. PWM is a plus, and very quiet.
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.
