Hey guys, he said that he touched it and it is not hot. 82 degrees C is like 179 degrees F, you would know in a heart beat that it was very hot.
As stated before, this is an important temperature, that's why the computer shuts itself down when it sees temperatures that high...real or not.
Just out of curiosity, download Everst home edition and see if the temperature match and see what the voltage reading for the cpu is. Also look to see what the temperature is when you first start the computer.
Depending on the BIOS you may be able to reset the temperature to keep it working, this would mean that you would need a secondary monitoring system to watch for a real temperature increase. Another option would be to replace the sensor, it is either a thermistor or a diode.
