The measuring platform consists of a modified A7V333 motherboard from Asus and a temperature sensor evaluation kit developed by Maxim. The board was modified in such a way as to enable the measurement of both voltage and current on the processor during operation.
This makes it possible to take precise measurements of the power dissipation during operation. It simply results from the product of the current drawn multiplied by the drop in voltage on the processor. In addition, using the temperature sensor evaluation kit, the exact die temperature is read out and displayed on the controlling PC.
We used an additional temperature sensor at a distance of about one inch above the ventilator fan in order to determine the ambient temperature. The processor (AMD Athlon-XP-2400+) is then heated with the aid of a DOS program that guarantees a constant processor utilization of one hundred percent. Instead of thermal pads, we used Arctic Alumina thermal paste in all of our tests.
