Documentation of ETX-DC® Heatspreader and Cooling Solutions are provided at the customer section of the Kontron
Website.

ETX-DC® onboard fan connector

This section describes how to connect a fan to the connector located directly on the ETX®-DC. With certain BIOS-
settings it is possible to control the fan depending on the Active Trip Point temperature. The fan switches on/off
depending on the adjusted Active Trip Point temperature. In order for this feature to function properly an ACPI
compliant OS is necessary.

Note: The ETX®-DC BIOS supports only turning the onboard FAN ON/OFF. For additional support 3rd party software

is necessary.
