Summary

This is a remix from SethBon fan

I've done some modifications to add a USB-C power delivery chip adapter to put 12v on the fan from usb-C!
It's more common to have a usb-C charger/dock-in/battery than a DC-jack power nowadays!

My fan is to loud at 12v, with the chip I set it to 9v and it's perfect on the desk! It works on classic 5v usb too with this chip.

A upgrade can be to put a switch on the box to control one of the 3 dip switch to pass on 9 or 12v or let to 12v and add a PWM controller for the fan
