Chassis intrusion connector (4-1 pin CHASSIS)
This connector is for a chassis-mounted intrusion detection sensor or switch. Connect
one end of the chassis intrusion sensor or switch cable to this connector. The chassis
intrusion sensor or switch sends a high-level signal to this connector when a chassis
component is removed or replaced. The signal is then generated as a chassis intrusion
event.
By default, the pin labeled “Chassis Signal” and “Ground” are shorted with a jumper
cap. Remove the jumper caps only when you intend to use the chassis intrusion
detection feature.

CPU and chassis fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN)
Connect the fan cables to the fan connectors on the motherboard, ensuring that the
black wire of each cable matches the ground pin of the connector.
Do not forget to connect the fan cables to the fan connectors. Insufficient air flow inside
the system may damage the motherboard components. These are not jumpers! Do not
place jumper caps on the fan connectors! The CPU_FAN connector supports a CPU fan of
maximum 1A (12 W) fan power.
Only the 4-pin CPU fan supports the ASUS Fan Xpert feature.
