    It's basically intended as a protection circuit - if the fan stops it disables the CPU to prevent it overheating. I suspect this might have been done because of the experience Sega had with the Model 3 cooking itself to death if the fans stopped working - gating off the clock if the fan stops prevents the chip from getting hot and forces the user to fix the fan.
