Core Temp is a compact, no fuss, small footprint program to monitor CPU temperature.

The uniqueness of it is that it shows the temperature of each individual core in a each processor in your system! You can see in real time how the CPU temperature varies when you load your CPU.

Intel and AMD recently published detailed, public information about the "DTS" (Digital Thermal Sensor), which provides much higher accuracy and more relevant temperature reading than the standard thermal diode sensors do. (How it works).

This feature is supported on all Intel Core and Core 2 series of processors as well as the whole AMD´s AMD64 line of CPUs. (for a full list of supported CPUs: (CPU Support List).

Core Temp also has a logging feature, allowing a user to easily record the temperature of his processor(s) over any period of time, then the data can be easily transfered into an excel datasheet for easy graphing.
