Fan Headers
There are three 4-pin fan headers on the motherboard. Although pins 1-3 of the fan headers
are backward compatible with the traditional 3-pin fans, we recommend you use 4-pin
fans to take advantage of the fan speed control via Pulse Width Modulation through the
thermal management. This allows the fan speeds to be automatically adjusted based on the
motherboard temperature.

Chassis Intrusion
A Chassis Intrusion header is located at JL1 on the motherboard. Attach the appropriate cable
from the chassis to inform you of a chassis intrusion when the chassis is opened. Refer to
the table below for pin definitions.
