Or even go further back to basics, check the board over for
extraneous "bits", put in a known working, bootable ,SD card, place
on on something clean and non-conductive and apply power does it come
up? As judged by the flashing of the lights. I don't think a Pi4
*needs* a fan for just a minute or two.

The only Pi I've killed was the result of accidentally putting +5 on
a GPIO line. Boot problems occasionaly but reseating the card
normally cures that on.
