Thermal Considerations

Figure 20 shows the locations of the thermally-sensitive components. Table 47 lists the maximum
component case temperatures for motherboard components that could be sensitive to thermal
changes. Case temperatures could be affected by the operating temperature, current load, or
operating frequency. Maximum case temperatures are important when considering proper airflow
to cool the motherboard.
A Slot 2 (Application Processor)
B Slot 2 (Boot Processor)
C Battery Case
CAUTION
An ambient temperature that exceeds the board's maximum operating temperature by 5
might cause components to exceed their maximum case temperature. For information about the
maximum operating temperature, see the environmental specifications in Appendix C. When
determining system compliance, consideration should be given for maximum rated ambient
temperatures.
