If I were to speculate
One of the techs decided to show that bumping the Amd hsf would also affect temps. Unfortunately the hammer that he used, caused the mobo to short, and made the system crash. He rebooted, but the shim that a different tech had installed, to show that Amds ran as hot as scotties, had been knocked out of place, so the hsf now made good contact with the chip.
That is ofcourse just a guess.
