Power cover for Ender 3s with quiet 8015 fan

This power case cover has a mount for 8015 fans, which is more quite than the original 6015 fan, and much easier to buy it from internet.
I choose a 12v 0.09a SanAce fan, really silent and cheap.It cost me 12 yuan(about 2 dollars) with shipping, half cheaper than 12015 fans for ATX.
But the original 12 volt joint can't turn the new fan on somehow, you will need a 24v to 12v board to make it work.

Take particular care with AC circuit, operate the power supply wit
