This is a new program that allows you to monitor Intel's "Core", "Core 2" and all AMD K8 chips' die temperature.
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
Note:
If you have problems downloading Core Temp v0.9.0.91,
please try to stop using your download manager
and avoid right clicking on files. Also, check
your firewall settings, because some mirrors may
require that you do not block the HTTP
referrers.
