Welp, my brother-in-law looked at the fan in the case and the one in the power supply, and they both seemed to be running slow.
He blew the dust off with some canned air and their performance seems a little better.
While he was in there, he looked to see what size power supply I had.
Come to find out it was only 170W or close to it.
That really surprized me. I thought I had at least a 350.
He told me Dell usually puts in parts that will get the job done with minimal effort.
I don't know the veracity of that statement, but it seemed true in this case.
Anyway, I'm going to buy a better power supply and a better case fan. Hopefully this will solve my problem.
Thanks guys, for all of your help and advice. I really appreciate it.
