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.

7. 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.

system may damage the motherboard components. These are not jumpers! Do not place
jumper caps on the fan connectors!
