One thing I noticed when exporting my computer specs to a HTML file from CPU-Z is my CPU temperature. It said that my CPU core temperature was 81 degrees Celsius.

This computer has run hot ever since I got it. And not just barely hot, it puts out hot enough air on the vents that holding your hand near it for too long (~30 seconds) will become extremely uncomfortable.
When I ran Speccy on my desktop, the highest temperature I think I saw was 55*C. I did a quick Google search for laptop CPU temp ranges and 70*C can be considered high.
Any thoughts or suggestions? Perhaps it is overdue for an internal cleaning, as I haven't cleaned it out since I purchased it two years ago when it was refurbished. The cooling system seems to be working as it is putting out fairly hot air from the vents, and the base pan barely gets hot.
