18 FAN Interface
Some EPIC/CEs can be equipped with a fan. If a fan has to be changed or added, use this interface to
connect a fan to cool the CPU. The connector and onboard system controller monitor the fan’s speed.
This connector supports 5V fans only.
18.1 Connector
The fan interface is available on Connector J1 (3 pins). For the location of the fan connector see
Appendix E: Connector Layout.

Notes
: (*) To protect the external power lines of peripheral devices, make sure that:
-- the wires have the right diameter to withstand the maximum available current
-- the enclosure of the peripheral device fulfils the fire-protecting requirements of
-- IEC/EN 60950.
18.2 Configuration
You can set the active trip point to a value from 40°C up to 100°C in the ACPI Control submenu of the
BIOS Setup Utility. The fan will automatically turn on whenever this trip point temperature value is
reached. Setting this item to disabled means the fan will always run, except when the operating system
takes control of it.
