    Replaced 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

    Always love Noctua fans, the quietest of the fans out there as far as I know.

    This fan is quiet, and the specifications are honest. Personally, I dont care for the colors. But from the packaging down to the sheathing on the wires, you can tell this is a high quality product.

    Great fan, quite. But Jesus, why did they make the thing so dam ugly. Tan and white? Really?

    Excellent replacement for an OEM fan on IC-7300. Almost noiseless. Took a little work (see various websites), but worth the $, work, and time.

    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!

    Installed this under the Swiftech MCP 35x2 heatsink and it works great. Theres not much clearance at all, but it does a beautiful job at cooling the pumps. PWM is a plus, and very quiet.

    These things are expensive, but I think they are worth the price. They push a large amount of air, and are the quietest fan I have ever seen. Also, Noctua stands behind their products. A friend of mine had an issue with his, and they quickly replaced it.

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.
