My laptop I am on now is sitting on my desk and will be running all day. Since it is on my open desk it gets plenty of airflow and never gets too hot. But when I take it home and have on my lap, it will get toasty after an hour of use.

I had a Toshiba that had this exact same problem, among many others. It also was turned in under the lemon law. It was a nightmare! Thank goodness it's gone!! I now have a Sony, and no longer have the problem.
I was told if the fans are dirty, that they would not work effectively and would contribute to overheating. Several times my old laptop was sent in for service, and they would just clean the fans. It did not fix the problem, but it did seem to help temporarily.
I also know they make chiller mats, which is basically a board with built in fans which help dissipate the heat also. They plug into a USB port.
Good Luck!
