My 6 year old gaming laptop did the same. I took it apart cleaned the dust and hit the fan with silicone based lube. Still kept overheating, so took another peek. I separated the fan from the processor and yeah...the heat paste looked like a dry riverbed in the Gobi desert. Scraped it off, polished both surfaces with 91% alcohol (DO NOT USE 70%/RUBBING ALCOHOL) and laid down some new arctic silver and all is right with the world now.
