Noctua NF-A8 PWM, Premium Quiet Fan, 4-Pin (80mm, Brown)

> 3 dayAs usual Noctuas quality doesnt disappoint. Most 80mm are just simply too weak. The NF-A8 moves air similar to a 120mm fan and its probably because of the max 2200 rpm speed, but its quiet at high speeds!

Greater than one weekA bit more expensive than most fans of the same size, but they are rather quiet and will move air effectively. I have a pair in the back of a rack-mount computer case and it does the job well, quietly.

Greater than one weekGreat upgrade for the old fans in my PC case. Noise level cut by 90% as compared to a molecule fan from 2003. I know that’s not much to go off of but it changed my PC so much for the better, no reason not to go noctua every time.

> 3 dayI had a weird case that I needed to get these for to replace some noisy stock fans, the extra kit you get with this fan is amazing. You get a y splitter, an extension cable, and a low voltage (silent mode) adapter. And on top of that it is a Noctua fan and the hype surrounding these fans is real.

14-11-2024Replaced stock fan in our nx300d amplifier with this fan. A bit of a passion to do but the sound reduction is pretty amazing. I suspect it also moves a bit less air but am very happy with the compromise

> 3 dayGreatly helped with keeping my server cooler and lowered the sound produced by my server.

> 3 dayThese are easily the best 80mm fans you can buy. I bought a couple of them to cool a 750Ti which I removed the stock fans and fan shroud. They are literally silent. They are impossible to hear if they are turned down using the motherboard. I even replaced my standard light bulbs in my room with LED ones because my computer was so silent I could hear them humming and that was starting to drive me crazy... but Im pretty OCD about things like this.

> 3 dayI used this Noctua NF-A8 PWM, Premium Quiet Fan to replace a functioning, but very loud fan. I had previously purchased a Noctua double fan unit for a CPU that was hitting Temps over 99C and it brought those Temps down to 54C - a very reasonable number. So it was so much easier to find a replacement side panel fan with the same name. With this fan my motherboard stays around 44C/CPU 48C (6 Core AMD Processor). This is important because I have computers that use folding@home software to fight a variety of diseases including COVID 19. The program is demanding so cooling is an absolute must. In the future should I need another fan - Noctua will be the brand!
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.
