This is a custom mount for a 120x120x25mm 5V USB fan for the original Prusa i3 MK3 PSU.
I placed the PSU outside of the enclosure, but it still gets really hot, specially in the Summer. So I decided to use a 5V USB fan to cool it.
The 120x120x25mm USB fans are really silent and provide enough CFM to cool down the PSU. I've been using it for a few months and the difference in temperature at touch is really noticeable.
You can use 12V or 24V 120x120 fans, but they may not be as silent.
