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, Chassis, and Power fan connectors (4-pin CPU_FAN, 3-pin
CHA_FAN, 3-pin PWR_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.
