Yes, cooling fans are always on when the ac is on and the car is not moving, this is normal, otherwise ac wouldn't work. condenser needs air flow at all times. As for the overheat, this tells you that the pcm is in control of the cooling fans. Either it is not getting the proper temperature from the temp sensor, which is located by the t-stat, or the coolant is low/air pocket, or you don't have the proper 50/50 antifreeze mix etc. is the check engine light on? does it idle rough after it is warm? check the simple things first.
