Greater than one weekWow this is a QUIET tiny fan . Used it to replace a different brand 40mm fan and the noise reduction was immediately apparent. I have to stick my finger in the fan to even know its working its that quiet.

> 3 dayI 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.

Greater than one weekUsing this on my Ender 3 and had originally thought it did not work it was so quiet!! The PSU fan is now the loudest fan on my printer.

Greater than one weekThe fan is quieter than a typical cheap fan you can find online. However, it doesnt seem to be as quiet as I would expect for a fan from Noctua especially at this price point. However, this being a 5V fan, it does work quite nicely off USB power (adapter required).

> 3 dayPerfect fan for a Dreamcast fan mod (3D printed mounting hardware available on eBay). Its quiet and it moves a surprising amount of air despite being tiny.
