Figure 30. Localized High Temperature Zones
Table 45 provides maximum case temperatures for components on the Desktop Board D865PERL
that are sensitive to thermal changes. The operating temperature, current load, or operating
frequency could affect case temperatures. Maximum case temperatures are important when
considering proper airflow to cool the Desktop Board D865PERL.
