Localized High Temperature Zones
Table 39 provides maximum case temperatures for Desktop Board D845GVFN components 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 D845GVFN.
