Greetings Ragnarok,
Notebook computers can be easily overheated. Here are a few reasons why:
For Windows users, there may be a process running in the background that eats up alot of the CPU. When this happens, your computer thinks harder causing it to overheat. The svchost.exe issue did that to a notebook I previously owned, and after a while it fried out the hard drive. Try looking in your Task Manager for any high "CPU Usage", and try to disect which process is doing that.
Another tip, try elavating the notebook from solid surfaces. Try to find an object and place it under the back part of the notebook so it looks as if the notebook is escalating. Just rising the back part of the notebook should allow more circulation and air-flow.
Notebooks tend to heat up when constantly thinking, mostly.
I recently replaced my Notebook hard drive, and installed SuSE Linux 9.1 on it. It's quite nice now, and I haven't had any overheating problems lately.
