Do you have gkrellm
installed? If not, I'd recommend it. It's an excellent, overall system monitor that displays many of the most important system values, including temperature. Obviously, if you do have an overheating problem this will not solve it, however, gkrellm will enable to you to easily determine what your temp is. (BTW the normal range typically will be in the high 30's or low 40's Celsius, if you see sustained periods where it's in the 50's or higher, it's running too hot) Good luck with it -- J.W.
