I thought it would be you :)
Have you checked what's running, the more work the PC and also graphics card does the hotter it will run. Is it like that just browsing the web say, or are you running tasks, games ? etc
Have you considered a laptop cooler, a little "tray" it stands on with inbuilt fans. These plug into USB port for power.
If it's Vista make sure you are running the "balanced" power plan, not "High performance".
