> 3 dayPurchased 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!!!

> 3 dayPut in a Honeywell fan enclosure to replace the existing 80mm which the bearings went out on. This is working as it should. I expect it being Noctua to last a while. Very low noise compared to the stock fan.

> 3 dayI installed this fan as replacements in two of my HP desktop computers with fans (both Cooler Masters) that had failed at nearly the same time. (planned obsolescence?) The Noctua NF-A8 PWM fans came with more than enough additional hardware, mounting options and electrical connections to facilitate replacement. I removed the old fans and heat-sinks. Cleaned mating surfaces of CPUs and heat-sinks and applied fresh thermal compound (Noctua NT-H1) and reassembled to motherboards. Both replacements performed perfectly and were very quiet as well as efficient. Both PCs run 54 watt Intel i3 CPUs and average temps are 28C at idle per Core Temp app, and never exceed 57C while under load test. I am well pleased. A great value for a reasonably priced fan with superior performance.

Greater than one weekThis review is for both the 92mm and 80mm versions of this model, 4-wire units with speed controlled by the motherboard.

> 3 dayWorked great, so much quieter than the foxconn heatsink fan i had before.

> 3 dayFeels well made, delivers on how quiet it is. Could probably cost half as much if the extra 3 cables I dont need and fancy packaging were optional.

> 3 dayA Great running quite fan with a 4pin hookup to the power fan link on the computer motherboard- Speed regulates depending on the internal temperature of the processor

> 3 dayThe quietest fan Ive ever used.Easy to install.
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.
