Not sure what guages you are using to read the temp, but if it is a mechanical one, you might want to test it (it is fairly easy) to be sure the readings that you are getting are accurate. I struggled with a similar problem years ago and then discovered that my guage was reading 15 degrees high and I really didn't have the problem that I though I had.
Just a thought.
