Might be time to replace the thermal paste between the proc and heatsink. In order to do that, you need to remove the heatsink, scrape the old thermal paste off of the top of the cpu as well as the interface pad of the heatsink with a plastic scraper (never use anything metal on either) and apply the new thermal paste. If you are not sure that it's the cpu that's overheating, d/load a program called Speedfan and it will tell you what exactly it is that's running hot, as well as all your fan speeds (obviously). It interfaces with the thermal sensors in the motherboard, cpu, gpu, etc. and displays them for you.
