WebTemperature is measured in degrees Celsius and measurement resolution is 1 degree C. Valid temperatures are from 0 to TjMax degrees C, because the actual value of temperature register is in fact a delta from TjMax. Temperature known as TjMax is the maximum junction temperature of processor. Intel defines this temperature as 85C or 100C. On linux, you can read it using rdmsr (read model specific registers) On ubuntu, you could try something like the following: sudo apt-get install msr-tools sudo modprobe msr sudo rdmsr --bitfield 15:8 -c 0x00001a2 sudo rdmsr --bitfield 23:16 -c 0x00001a2.
