One more. This Pi got so hot it left melt marks on the enclosure 
. Eventually CPU died.
It was one with MXL7704-P4 PMIC so that CPU I tried to install earlier worked perfectly fine.
So indeed it seems like different CPU chips are meant to work with different PMICs.
P.S.: It amazes me how these days reballing and replacing a CPU feels like a quick and easy job - something that was unthinkable just a few months ago 
.
Guess what - found a CM4 with a dead CPU as well. Same exact chip version again. Replaced it with a seemingly good one from another donor, but don’t currently have a carrier board to test if it really works. Ordered one, but will receive it in a few weeks
