Engine running hot

I write so many posts on here that I wonder about this car...
I do love it though.

My car is now in Las Vegas and since fixing up the temp gauge I find that the car is running 110 to 118 all the time. AC on or not. This seems quite high to me. New rad cap, coolant change. My aux fan is rigged to run all the time.

How can I cool this down? I take it I should be worried somewhat about this.
