Fan runs too much when I run a certain application

I've looked at all the other threads about the fan running too much. I have already reset the SMC and that is not doing the job. The fan runs fast only when I use the application Pycharm. Pycharm is a Python working environment. Admittedly, Pycharm is a large application which takes up 400 megs. When I look at the activity monitor it takes up between 100 - 300% of the CPU. I frankly don't know how anything can take up more than 100% of the CPU but it does. I've seen with other threads on this issue that sometimes the problem is solved by throwing away a small file so I hope that works in my case.
