re: Laptop overheating help

I am not sure what you did to clean it, but I typically blow all of the dust out of mine with canned air a couple of times per year....

fwiw, it sounds to me like you have a fan or two that is going out...have you looked to see if the fans are turning when this happens? I am betting that you probably have one fan that does not work and another that is making noise because it is going out...
