Test Results

Test Scenario 1: Dual Core EPU-4562-EBP – Passive and Active Thermal Characterization
Shown in in the figure below, running the test scenario with just the heat sink, the core
temperature is slightly above 100 ºC at maximum ambient temperature. This will be less in most
applications that require less than 90% CPU utilization. Adding the fan provides an additional 5-
6 ºC of margin. For long-term reliability, ensure the CPU cores are predominately running with
their temperatures below 100 ºC.
