I suppose you could splice a toggle switch into one of the wires going to this sensor (I think it is the coolant temperature sensor). When you flip the toggle switch open, it should do the same thing as dis-connecting the switch. The next step in convenience is to extend the toggle switch and mount it in the dash, where you can turn it on and off from inside the car.

You could do a similar thing by splicing a toggle switch into the a/c pressure cut-off switch, that mounts into the high pressure a/c line. Connecting two of the wires from this switch will activate the high speed fan.
