Noctua NF-A8 PWM, Premium Quiet Fan, 4-Pin (80mm, Brown)

Greater than one weekMy Dell G5 desktop absolutely sounded like a vacuum sweeper with only one exhaust fan that constantly ran full blast except for when it was shut down. I installed two 80mm Noctua exhaust fans and two intake fans with the included low noise adapter cable and now its so much quieter.

13-11-2024I 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.

> 3 dayExcellent fan!! Works flawlessly, although that was to be expected with noctuas quality. Fan is silent at low rpms, and not too loud when ramped up.

> 3 dayAlmost silent compared to what I took out. I used the rubber pull through mounts and it was very easy to put in.

> 3 dayGreat fan. Perfect for my custom build. I used it in a tight spot to feed outside air to the 3 stock fans of my 1080ti. The card has never exceeded 58 degrees C. and my hot m.2 ssd sits right under the intake of the third fan. Very very happy I am.
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.
