6.1 Thermal Management
A heatsink assembly (38010-0000-99-0C02) is available from Kontron Embedded
Modules for the ETXexpress®-AI COM. The heatsink fits on top of this assembly
and serves as an active cooling solution.
The optimum cooling solution varies, depending on the COM Express™
application and environmental conditions and the module is fully functional
at the full 0°C to +60°C temperature. Drawings for the active heatsink are
available on request. Also, see the PICMG COM Express™ Design Guide on the
PICMG website for further information about thermal management.
6.2 Onboard Fan Connector
This section describes how to connect an optional fan to the connector
located directly on the ETXexpress®-AI COM.
Figure 8: Fan Connector Location and Pin-Out
