If the car is just sitting and idling and you turn the electric fan on, it should start to go back down pretty fast. A mechanical fan will try to keep it around the temp of the t-stat or the lowest the combo can run. It sounds like your electric fan isn't working well enough by itself so try the shroud. If that doesn't bring it down then the fan itself is a problem or the coolant isn't circulating properly or could be geting aerated by the pump.
