5. Digital Audio connector (4-1 pin SPDIF_OUT)
This connector is for the S/PDIF audio module to allow digital sound
output. Connect one end of the S/PDIF audio cable to this connector
and the other end to the S/PDIF module.
The S/PDIF out module is purchased separately.
4. CPU, Power and Chassis fan connectors
(4-pin CPU_FAN, 3-pin CHA_FAN)
The fan connectors support cooling fans of a total of 1A~2.2A (26.4W
max.) at +12V. Connect the fan cables to the fan connectors on the
motherboard, making sure 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.
