WebNov 12, 2015 · In order to read the IA32_THERM_STATUS register you use the asm instruction rdmsr, now rdmsr cannot be called from user space code and so you need some kernel space code (maybe a device driver?). 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.
