I need help with my CPU Overheating. It's an AMD Phenom II X6 1055T @ 2.80GHz. Everytime I play CS:GO, about 5 minutes in, my CPU will heat up, and my PC will shut off. Upgrading anything or buying a fan is not an option. I would like to know what I should, or how I could clean out my CPU Heatsink's fan.
