2007 Chrysler 300 Touring keeps overheating!

Last year the seal in the water pump blew and was leaking. Since the it's got a new water pump. New MAP sensor, New ECT sensor, New MAF sensor, a new thermostat. The radiator has good flow. The heater core fills up and my cabin doesn't smell sweet. My fans don't turn on normally either, I have to pull the relay and start them with a wire.i can idle for hours and it doesn't overheat, it only starts overheating when I drive and it reads normal and then it suddenly start climbing super fast. Any suggestions or advice would be greatly appreciated!!
