COMe-bCD2 onboard Fan connector

This section describes how to connect a fan to the connector located directly on the COMe-bCD2. 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 COM Express® CD BIOS supports continuous fan control in order to accommodate the CPU temperature
characteristic curve.
