5. Digital audio connector (4-1 pin SPDIF_OUT)
This connector is for an additional Sony/Philips Digital Interface (S/PDIF) port. Connect
the S/PDIF Out module cable to this connector, then install the module to a slot opening
at the back of the system chassis.
The S/PDIF module is purchased separately.
6. CPU, chassis, and power fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN1/2; 3-pin
PWR_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 the CPU fan of maximum 1A (12 W) fan power.
• Only the 4-pin CPU_FAN, CHA_FAN1/2 connector supports the ASUS Fan Xpert
feature.
