> 3 dayOn a motherboard with good automatic speed control, this fan is nearly completely silent in normal operation.

> 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.

> 3 dayI bought a Dell 3880 and its a great little system... EXCEPT THE CPU FAN IS TOO NOISY. If youre in a quiet environment then you will almost certainly notice the noise.

> 3 dayI thought, wow, this is a super quiet fan. Then I realized that it just didnt work at all.

Greater than one weekGreat fan that came with a lot of extras (stabilizers, rubber feet to decrease noise, and multiple options for connecting it). Only issue is that it is about 2mm bigger between the holes than it says. This probably is not an issue for most (as this fits a standard configuration in a computer) but it did not work for my purposes (replacing a noisy fan in my aquarium hood). 4 Stars because of the misfit, and because I had to order this twice (the first time it never showed up, but amazon refunded my money so it was all good).

Greater than one weekGood air flow but a little loud at full rpm. Speed control and rpm feed back to BIOS.

> 3 dayI had a bit of a nerve-wracking experience installing it -mostly due to the high stakes (it is my cpu, after all!) and lack of experience. But everything I needed was there and since installing it Ive largely forgotten its even there.

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.
