Thermal/Cooling Requirements

The CPU is the primary source of heat on the board. The CoreModule 920 is designed to operate at the
maximum speed of the CPU and requires an active heatsink for extended temperatures (optional). A passive
heatsink is available (optional) and allows maximum speed operation within the Standard temperature range.
The passive heatsink will allow operation in the Extended temperature range if the CPU speed is locked at
800MHz. To lock the CPU speed at 800MHz, use the Power Consumption setting field in the CPU/PPM
Configuration submenu of the
measurements of the cooling assemblies.
