So, how would I prevent this 12v power supply from overheating... as I'm guessing the issue is that the power has no where to go and is just being held in the wires.

Only with a posted schematic drawing of your complete wiring setup can anyone do more then a wild ass guess of what might be wrong. Lefty
What is the spec of the 12V supply?What is the rating of the desktop fan?Is the supply powerful enough to drive the fan?Bear in mind breadboard connections are good to 200mA to 500mA or so, put too much currentthrough and you'll ruin it - high current wiring best done with screw connector blocks which arerated 5A, 10A etc.BTW the common ground point is ideally at the motor driver since thats where signal levels meet high-currentcircuitry.
like I said I know nothing of circuits
I'm curious in what usual case would the power supply overheat if a circuit is in the off position vs it's allowed to run?Is there some sort of code that could stop the current from being drawn? I think when my switch is off, I'm drawing a current, but not doing anything with it.
I know the Arduino is specifically supposed to use solid wires for the circuit,
Yea, I might get around to drawing a circuit for you guys.
(well actually multimeter time is after putting the circuittogether and _before_ first applying power - always check for power supply shorts with a new circuit).
