I think this would require a hall switch, an IC of some kind (*see electronics noob disclaimer) and a a pin header on a very small circuit board, and connect to the motherboard pin header with your typical 3-wire connector.
*I don't know even a modicum of electronics so I don't know exactly how to translate a hall switch's output into a fake rotation speed (0 or otherwise).
If anyone here thinks/knows is this is feasible, please speak up.

problem with this solution is that if there is a leak... the pump will continue untill it is dry... yet still rotate...
you could have no water in your loop but still have active signal comming from the pump...
i have done the
AquaXtreme or MCP-600 R.P.M. Signal Mod. myself so i know if my pump is roatating and and at what speed...
but the system won't shut my machine down if all the water leaks out of the loop.
