Cooling Fan Connectors
The fan connectors are used to connect cooling fans. The cooling fans will provide adequate
airflow throughout the chassis to prevent overheating the CPU and system board components.
BIOS Setting
The Advanced menu (“Hardware Health Configuration” submenu) of the BIOS will display the
current speed of the cooling fans. Refer to chapter 3 for more information.

Chassis Intrusion Connector
The board supports the chassis intrusion detection function. Connect the chassis intrusion
sensor cable from the chassis to this connector. When the system’s power is on and a chassis
intrusion occurred, an alarm will sound. When the system’s power is off and a chassis intrusion
occurred, the alarm will sound only when the system restarts.
MyGuard Hardware Monitor
Install the “MyGuard Hardware Monitor” utility. By default, the chassis intrusion detection func-
tion is disabled. When enabled, a warning message will appear when the chassis is open. The
utility can also be configured so that a beeping alarm will sound when the chassis is open.
Refer to the “MyGuard Hardware Monitor” section in chapter 4 for more information.
