> 3 dayI ordered a new fan, but it is clearly a used product, look at the pictures. Dont buy here it can happen to you as like me. First time that happend to me in Amazon. Buy from another seller. At least the fan works and it is silent.

> 3 dayUsing them in my TT mini cube T1 case. They move a lot of air and keep the motherboards voltage regulators nice and cool. They are super quiet, even at full speed.

> 3 dayI got this fan as a replacement for a hard drive enclosure. The fan is a bit wider than the standard, but this is still by far the best fan you can get.

> 3 dayI forgot I had these. Seriously... They were so quiet I forgot I bought these/they existed at all. It moves a ton of air and couldnt be happier! :D

> 3 dayNoctua fans are no joke. Fans quieter @ 2200rpm than some 140mm @1300rpm.

> 3 dayI replaced both my CPU fan with an 80mm and my case fan with a 92mm version of the Noctua fans. The are very quiet and seem well made. Box included 3 additional cables, screws and rubber mounts in case I needed to use them... Didnt need for my install, but nice touch! Very happy and recommend them!

Greater than one weekI replaced the stock fan on my ICOM IC-7300 transceiver and it is much quieter. The unit moves more than enough air to keep my rig cool during long transmissions at full power. Exact details for making the change-out are available on the web.

> 3 day2 80mm fans added to my new Dell G5. Easy to install and keeps my processor below 75c.
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.
