What else do you have running? There should be no reason you are running hot. Maybe look into your cooling system? Never hurts. I run a dedicated server, run the game and another server launched via the game and never go over 60 degrees on the CPU that I can remember... sitting at 53.8 right now with GPU at 59.7

Even if I run benchmarks for hours at 100% CPU and 100% GPU nothing ever goes over 75.
