Heat is a big problem with a lot of laptops. They just dont have adequate ventilation. Really your best thing do to would be to take it apart and put a high quality thermal grease under all the heatsinks and maybe engineer the ventilation channels a little bit better if possible. Ive done those things quite a few times.

If your not in to tearing apart your laptop (not recommended unless you have an idea of what you are doing - most of them are like jigsaw puzzles), then you can get one of those laptop coolers that attach to the bottom of your laptop and help pull the heat away. Most of them have like 2-5 decent size fans in them. I have a friend that was having overheating issues with his lappy but no longer is a problem since he put the cooler on. I am pretty sure newegg.com has them, but I am not positive.
