There are two main things that affect the temp. One is the dial setting, but what is equally important is how fast or how slow you draw. The faster you draw, the cooler the temp. The slower you draw, the hotter the temp. The best way to find that sweet spot is to leave either your draw speed or the temp setting constant and just vary the other one. If you vary both at the same time it will be that much more difficult to find that sweet spot.
