    At first my PC sounded like it was ready for takeoff and now I can barely hear it. It keeps my PC cooled and its not noisy. 10/10 would recommend

    Can’t seem to go wrong with these fans.

    Replaced the 80mm fan on the back of my 12 drive cage. The computer is silent again.

    doesnt move a LOT of air, but its silent.

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

    Pleantly surprise to see a conservative spec on noise reduction. The Noctura fan was better than its published spec.

    Good as it gets.. and then some. Youll forget its there.

    Very well made, excellent cooling, and nearly silent.

    I have a 50 watt grow light in my living room and the original fan was too loud. I searched quite fans and found this. I didnt realize how loud the 1st fan was until I got this and could compare thsm. It has 2 speed settings and both of them are ridiculously quiet. Considering how cheap they are you cant go wrong. I dont think its just the rubber mounting attachments that are on the fan, but the fan itself is just really quiet. I am using 2 of them for LEDS and neither one is housed in any enclosure that would dampen the sound. They are both open, visible and super quiet. Highly recommended!

    Amazingly quiet in ICOM 7300

NF-A8 PWM headerNF-A8 PWM header

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.
