Wow, thanks alot.
Hm, oh, I thought pwr_fan connector is where the psu fan monitor is supposed
to be plugged, hence the label.
The problem with CHA1 is that it's located WAY down at the bottom of the
board.
The fan monitor cable of the PSU won't reach that far.
Great info though, and it makes sense.
