Internal I/O Connectors
These fan connectors are used to connect to cooling fans. Cooling fans provide adequate air
circulation throughout the chassis and dissipate heat to prevent overheating of the system
board and components. The 4-pin fan provides PWM to modulate fan speed whereas the 3-pin
fans modulate fan speed via voltage modulation.

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.
