Greater than one weekAlways love Noctua fans, the quietest of the fans out there as far as I know.

> 3 dayBought several of these. Used them as case fans and also to replace two powersupply fans on older Antec Basique 500w. Quiet reliable fans, working for few years already without an issue. Using the provided resistors makes them even quieter. Will not consider other brands.

> 3 dayBest fan manufacturer Ive found. Ive experienced fan failures and excessively noisy fans over the years, but never from a Noctua. I use them in all my computer cases anywhere a fan will fit, and my first Noctua CPU fan/heat sink combo (NH-C14 on a 1st generation I7 processor) is phenomenal. A perfect compliment for an SSD, you may have to look twice to see if the PC is on!

> 3 dayFans are very quiet. The only fan I have left to replace is the power supply fan. It is the loudest.

Greater than one weekI 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!

> 3 dayWork quiet and good amount of air, a bit expensive than another but worth it.

> 3 dayThis was easy to install and i am an 65 year old with arthritic hands! They had different hardware depending on your need. Works great and not noisy. My desk top cabinet is right next to my recliner. I never hear it.

Greater than one weekGood product for my mini ITX build
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.
