Another very common cause is a blown head gasket. The combustion gasses displaces the coolant. Do you notice coolant loss and is there odor in the radiator....

You either have a Bad Water pump and its not circulating the coolant through the engine, or your thermostat is not opening to allow the coolant to release the heat through the Radiator. Also there could be air in the coolant System. Any of these can cause your engine to run hot and not set a DTC or Check Engine Light.
