5Thermal Metrology

The system designer must make temperature measurements to accurately determine the thermal performance of the system. Intel has established guidelines for proper techniques to measure the MCH case temperatures. Section 5.1 provides guidelines on how to accurately measure the MCH case temperatures. Section 5.1.8 contains information on running an application program that will emulate anticipated maximum thermal design power (Figure 5-1).

5.1MCH Case Temperature Measurement

Intel 5000 Series chipset MCH cooling performance is determined by measuring the case temperature using a thermocouple. For case temperature measurements, the attached method outlined in this section is recommended for mounting a thermocouple.

Special care is required when measuring case temperature (TC) to ensure an accurate temperature measurement. Thermocouples are often used to measure TC. When measuring the temperature of a surface that is at a different temperature from the surrounding local ambient air, errors may be introduced in the measurements. The measurement errors can be caused by poor thermal contact between the thermocouple junction and the surface of the integrated heat spreader, heat loss by radiation, convection, by conduction through thermocouple leads, or by contact between the thermocouple cement and the heatsink base. To minimize these measurement errors, the approach outlined in the next section is recommended.
