> 24 hourI 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!

> 24 hourVery well made and includes several different cable lengths. Just doesnt plug into my DELL MB fan header. My oversight. I have had twp DELL PCs and know most DELL PCs use proprietary components. The thing that really torques my hind side is that the ONLY adaptor I have found to enable me to use the Noctua case fan costs as much as I paid for the fan. If I want to use the Noctua fan,I am going to have to find an adaptor, and I can tell you they are scarce. Bah Humbug DELL

> 24 hourGreat fan that came with a lot of extras (stabilizers, rubber feet to decrease noise, and multiple options for connecting it). Only issue is that it is about 2mm bigger between the holes than it says. This probably is not an issue for most (as this fits a standard configuration in a computer) but it did not work for my purposes (replacing a noisy fan in my aquarium hood). 4 Stars because of the misfit, and because I had to order this twice (the first time it never showed up, but amazon refunded my money so it was all good).

> 24 hourThese fans are very well made. They are extremely quiet and durable. I installed them into my 4U server that contains 24 hard drive bays. After switching the fans that came with the case for these the was no more hum. Just extreme quietness. I would recommend these fans to anyone looking for a great quality made fan.

> 24 hourI 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.

> 24 hourI 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.

> 24 hourNice quiet fan. Does not move much air.
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.
