5. CPU, Chassis, and Power Fan connectors.
(4-pin CPU_FAN, 3-pin PWR_FAN, 3-pin CHA_FAN1)
The fan connectors support cooling fans of 350mA~740mA (8.88W max.) or
a total of 1A~2.22A (26.64W 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.
6. Digital audio connector (4-1 pin SPDIF_OUT)
This connector is for an additional Sony/Philips Digital Interface (S/PDIF)
port(s). Connect the S/PDIF module cable to this connector, then install the
module to a slot opening at the back of the system chassis.
Only CPU Fan supports Q-Fan.
The S/PDIF module is purchased separately.
