Noctua NF-A4x10 5V, Premium Quiet Fan, 3-Pin, 5V Version (40x10mm, Brown)

Amazing fan. Saved me a bunch of time and money as its easy to install.

I used this to repair a fan in an old ClearOne XAP 800. It worked beautifully without making a lot of noise. The installation kit was very complete and i didnt worry a bit about it possibly not being able to connect. It has been running non-stop now for a month or so with no signs of slowing down.

I originally had a Canakit case for my Raspberry Pi 4 Model B 4GB with the Canakit 30mm Fan. I wanted to mess around and overclocked the RPi from its base 1.5GHz to 2GHz but in order to do so I needed the max overvoltage applied which was level 6 which adds 0.15V I believe to the SoC. When testing the CPU under load using sysbench the 30mm fan would need to be at 5V and would be loud and nearly reach 80C which is near throttling temperature for the CPU. at 3.3V I couldnt hear the fan but it would throttle.

Perfect. I used these fans to replace the POS fans that came with amcrest DVR. They are working very well and are super quiet.

I bought this to install in a musical synthesizer, so noise—both mechanical and electronic—were of great concern to me. This fans seems to deliver on both fronts. Mechanically, the fan is whisper quiet. Its not silent—no fan is—but it is certainly not going to be heard on any of the mics in my studio. Electrically, I actually cannot hear any hum or noise in the output of my synth; it sound exactly the same whether the fan is plugged in or not. This is nothing short of miraculous, and saves me a lot of trouble working up a filter.

Well packed, loaded with extras (cables, screws, connectors), well built and very quiet. My Lorex DVR has been noisy from the factory and their support staff slow and not helpful. Took matters in my own hands and bought this fan. Wow, is it quiet and well built.

The only problem is that the cord is a bit too long for a MiSTer, but that is hardly a dealbreaker.

I used this to replace both the CPU fan and internal outward facing fan in my Amcrest DVR. It works really well and is extremely quiet, which was the issue I was having with the original DVR fans.

I read some reviews of people having trouble getting this to work at 5V. For me it ran just fine on the 5V and GND pins of the DE10 Nano board for the MiSTer project. If youre buying for that, have no worries!

Got the job done perfectly and is super quiet. Love that it comes with a 3 pin to 2 pin adapter in the box. 10/10 would buy again
