Chapter 4 provides information on the reference cooling solution for ATX systems. Intel’s reference boundary conditions for ICH8 in an ATX system are 60 °C inlet ambient temperature and 0.25m/s [50 lfm] of airflow. The ICH8 package will not require a heatsink when power dissipation is at or below 3.0 W.
Appendix A for the current reference ICH8 heatsink vendor information. The component should be operated above the minimum case temperature specification listed in Table 2. ® Table 2.

Thermal Metrology Thermal Metrology The system designer must make temperature measurements in order to accurately determine the thermal performance of the system. Intel has established guidelines for measuring chipset component case temperatures. Case Temperature Measurements To ensure functionality and reliability, the chipset component is specified for proper operation when is maintained at or below the maximum temperature listed in Table 2.
Figure 3 describes the recommended location for air temperature measurements measured relative to the component. For a more accurate measurement of the average approach air temperature, Intel recommends averaging temperatures recorded from two thermocouples spaced about 25 mm [1.0 in] apart.
