An electric fan should be activated by a coolant temperature sensor ands shut off when the engine is cool enough. The system is designed so that if the temp sensor fails, the fan will come on. That's called, "Fail safe" design philosophy. Test or replace your coolant temp sensor and it should run normally again.

Is defroster or AC on? Check the fan relays in the fuse box to see if they are stuck. Check the temp sensor.
