> 3 dayEasy to install and practically silent. Highly recommended.

> 3 dayVery pretty package. Very quiet. Expensive, but nice mounting options. Doesnt blow much air, but what do you expect from a 1400 rpm fan. I took a point off because of its cost.

> 3 dayBought this to replace a noisy fan in my switching power supply, installed without a hitch and works great. Best of all....its quiet. Hard to talk on my amateur radio with a noisy fan in the background. I had bought one for a replacement on one of my radios a few months earlier and couldnt be more satisified.

Greater than one weekFans are very quiet. The only fan I have left to replace is the power supply fan. It is the loudest.

Greater than one weekI got this to replace the loud slightly whiney foxconn cpu cooler in my HP Pavillion Ryzen 3600 gaming computer and it did lower the volume, and it even slightly lowered my CPU idle temps, but my cpu temps under heavy load from video rendering went from 64.5 to 74c. ( i found disabling the turbo boost brought the cpu temps under heavy load down to 55c). Too bad my case wont let me install an 80mm to 92mm fan adapter so I could install a quiet but powerful Noctua 92mm PWM case fan as my cpu fan. :( But for case fans you cant beat this fan if you value a silent computer.

Greater than one weekGreat packaging. All needed mounting hardware. Extension cables and splinter cables if needed for installation. Would buy again.

> 3 dayQuiet. Moves a lot of air. High quality fan for sure.
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.
