    Can’t seem to go wrong with these fans.

    It hasnt died or started squeaking, chirping or making any unusual noise. It runs relatively quiet for the expected amount of airflow. It does have onboard RPM sensors. Made a little bit of electrical interference noise running PWM, but works fine in DC. Chocolate Brown and Beige doesnt exactly match the black PCB and interior of my case, but may look right at home in your 80s performance build with a 5.5 Floppy. It does the job.

    Superior fan. Dead quiet. Everything is top notch. Cables are generous. adapters included.

    It is quiet and good quality. It comes with some connectors. Everything looks so pro, doesnt like other cheap PC fan.

    If you have to install two of these packed together all the rubber noise reduction will make this tricky. I had to put the screws on and angle to get the second fan in my case.

    Purchased Noctua NF-A8 PWM fan for multiple electronics upgrades. As with all Noctua fans, the NF-A8 is quiet and super efficient. Made with high-quality materials, the NF-A8 is perfect for any cooling application. HIGHLY RECOMMENDED!!!

    They may seem pricy. You might not like the color, but these are hands down the best fans money can buy. When they say ultra quiet, they mean it. I put them in an old NAS that was so loud that you could hardly stand to be in the room with it. Now it’s so quiet I forget it’s on, and it even runs cooler than before.

    I do a lot of audio and video recording in my office and have noticed a computer hum in some recordings. After doing some research I found out about these fans which as supposed to reduce noise. I pulled my computer apart to find out what I needed and ordered the replacement fans. They came in two days and I installed them. They looked good and fit perfectly, but I have been disappointed with the results. The noise isnt any better than it was with the original factory fans. I went through all that work for no change. So Im going to have to pursue a different and more drastic sound dampening approach. I wouldnt waste your time with these so called silent fans!

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 Channels

The 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 bearing

The 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 pads

Integrated 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

  • Low-Noise Adaptor (L.N.A)
  • NA-YC1 4-pin PWM y-cable
  • NA-EC1 30cm extension cable
  • 4x NA-AV1 anti-vibration mounts
  • Fan screws

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.
