Do not forget to connect the fan cables to the fan connectors. Insufcient air ow inside the
system may damage the motherboard components. These are not jumpers! Do not place
jumper caps on the fan connectors!
3. CPU and chassis fan connectors (4-pin CPU_FAN, 3-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.
The CPU_FAN connector supports a CPU fan of maximum 2A (24 W) fan power.

4. 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.
