Click on the "CPU" tab. There you can see the case temperature. A good guess is that the core temperature is 5C hotter.
The mobile processors can become quite hot, 70C for some time is not too hot. Some have a case temperature of 105C and with others the max is only 55C.
Seeing ?? please send me the log, so I can add your processor to the list.
If you know the temperature is off, because you saw it in another program, please report it to me so I can fix this in the next version.
