My laptop CPU is "Intel(R) Core(TM)2 Duo CPU T6500 @ 2.10GHz". I use Ubuntu 10.10 and I get the CPU temperate via 'sensors' program.
During normal operation it reports the CPU temperate ~50 centigrade. But if I run some long running CPU intensive program the CPU temperature shoots to 80 centigrade. And due to fear of burning CPU I do not run the program completely.
