is operating as designed you should not need any extra help. I used to live in TX and now in the middle of the Mohave Desert and I never run hot even when it is 130 degrees outside. I would suggest checking the thermostat and having your radiator boiled out. I have a sports car that was always runninng just below red. I did the electric fan and was going to get it rodded but a good cooling guy took a measurement with a heat gun and found out it was not running hot it was an electrical part that was causing my gauge to read high as well as gas and speedometer
