What is Prochot ThrottleStop?

PROCHOT is an emergency throttling method triggered when a CPU hits its maximum temperature (100 or 105C). You will often see this triggered on MacBook Pros, for example.

Should you disable BD Prochot?

Whether BD PROHOT is checked or not in ThrottleStop, your CPU will still be able to thermal throttle and slow down if it ever gets too hot. Your choice is to forever use ThrottleStop to disable the BD PROCHOT signal path or complain to MSI and try to get a new board.
