    On bottom edge of the MB next to ram slots there is a 3 pin connecter labeled (see page 9 of manual # 6 --6 Power Fan Connector (PWR_FAN1)) PWR_FAN1. What is it for?

    A "power fan" header is usually found on most mother boards. This fan header does not have any ability to change the speed of a fan connected to it. It supplies the full standard 12V to the fan at all times. You won't find any option in the BIOS or ASRock utility to adjust a fan's speed when connected to it.

    This header is useful for powering the pumps of AIO liquid CPU coolers that need the pump running at one speed constantly. If you have any fan that you want to run at full speed at all times, or a fan that has its own speed control built into the fan, this fan header is good for those purposes.

    I believe the term power fan came from the way some PC power supplies were designed ~20 years ago. The power supply's fan had to be connected to the mother board, or could be for some reason. So the name power fan for the power supply's fan made sense, and has become a tradition for mother boards.
