> 3 dayThey are OK but when you hook so many fans (4) to the mother board (with 750 watt power supply) some of the fans are struggling for power. Had to cut off off plugs and reattach power supply connections and then they work fine.

Greater than one weekThere’s a saying “you get what you paid for” and that’s the noctua fans. Noctua fans are the most expensive fans I’ve seen when I was building my $5000 pc. It’s crazy how quiet they can become. The noctua fans are considered ugly because it’s brown, but I actually like the beige and brown color. It’s a nice touch to any classic pc.

> 3 dayThis is the quietest fan Ive ever used - dead silent, in fact; however, the reason its so quiet is that it doesnt spin. When the computer starts, the fan spins for less than a second then does nothing, no matter how warm the computer gets. Ive tried several other fans on the same MB header, all work. The other fans are noisier than Id like, which is why I ordered this one. If, however, the tradeoff for a quieter computer is overheating, Ill endure the noise.

> 3 dayits so quiet its shocking not to hear any fan case noise when the PC is on, I thought it wasnt running but looked at the fans with a flashlight, and they spin, but are silent, good quality, really improves PC time with a quiet background

> 3 dayI used this fan to replace the stock fan in my Icom IC-7300, which was quite loud during transmit. The Noctura fan is essentially silent. I cant hear it at all. If youre looking for a quiet fan, look no more, this is the one.

> 3 daywould not run at POST and boot up until computer called for high fan speed. BIOS fan test failed. Fan test expected speed of 2600RPM; actual results of 4 test reported 1000RPM each test.

> 3 dayAt first my PC sounded like it was ready for takeoff and now I can barely hear it. It keeps my PC cooled and its not noisy. 10/10 would recommend

> 3 daySecond to none for quiet and cool, but more expensive than most.. worth it for me but some may not agree.
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.
