The PSU sounds like an ultra sonic cleaner! The fans seem to fail. My take is its just general case air movement... its not like a proper heat sync or critical exhaust fan but is beneficial obviously. Both power supply types can be used. You just have to unlatch the end red wire crimp and move to a spare 12v. I still think you might have another problem. I'd at least expect it to start booting. If you can use a multimeter you can measure the 5v while connected to the machine. If it dips bellow a threshold voltage I forget what so im going to guess at 4.8v-5.2v (Sega) the Scorp4 will keep reseting. Needs to be connected to the load (machine).

I did start it a few years ago, I'll have a dig through some old harddrives.
