Tcontrol; Figure 2-3. Example Thermal Profile - Intel CELERON PROCESSOR E3000 - THERMAL AND MECHANICAL DESIGN Design Manual

The thermal profiles for the Intel Core™2 Duo processor E8000 series with 6 MB
cache, Intel Core™2 Duo processor E7000 series with 3 MB cache, and Intel Pentium
dual-core processor E6000 and E5000 series with 2 MB cache, and Intel Celeron
processor E3000 series with 1 MB cache are defined such that there is a single
thermal solution for all of the 775_VR_CONFIG_06 processors.
To determine compliance to the thermal profile, a measurement of the actual
processor power dissipation is required. The measured power is plotted on the
Thermal Profile to determine the maximum case temperature. Using the example in
Figure 2-3 for a processor dissipating 50 W the maximum case temperature is 58° C.
See the datasheet for the thermal profile.
