Software Description

This is a new program that allows you to monitor Intel's "Core", "Core 2" and all AMD K8 chips' die temperature.

Attention - this is the OLD download section of, click here to visit the new and up-to date one.
The temperature readings are very accurate as the data is collected from a Digital Thermal Sensor (or DTS) which is located in each individual processing core, near the hottest part.
The way this program works is as follows:
Intel defines a certain Tjunction/TCaseMax temperature for the processor. In the case of Yonah it is 85C or 100C. First of all the program reads from an MSR, detects the Tjunction/TCaseMax temperature. A different MSR contains the temperature data, the data is represented as Delta in C between current temperature and Tjunction/TCaseMax.
So the actual temperature is calculated like this 'Core Temp = Tjunction/TCaseMax - Delta'
The size of the data field is 7 bits. This means a Delta of 0 - 127C can be reported in theory. But from preliminary tests, the reported temperature doesn't go below 0C, no matter what kind of cooling was used.

AMD chips report the temperature by a special register in the CPU's NB. The way the temperature is calculated like this: 'Core Temp = Value - 49'.
They can report temperatures between -49C and 206C
