Radiator fan blows very hard, not all the time but often when the car has been driven alot. No other issue with heat or anything just that the fan is blowing hard. No real issue aside from the fact that after standing still idling the car gets cold and doesnt blow as hot as when the car was under load. Its almost as if the fan blows so mich the engine gets a little colder than operating temp. Its hard to describe but the fan is making alot of noise. Just blowing noise no bad sounds or anything like that its just a loud fan noise. Anyone got any ideas
