4. CPU Fan connector (4-pin CPU_FAN)
The fan connector supports cooling fans of 350mA~740mA (8.88W max.)
or a total of 1A~2.22A (26.64W max.) at +12V. Connect the fan cable to the
fan connector on the motherboard, ensuring that the black wire of the cable
matches the ground pin of the connector.
5. 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.
CPU Fan supports Q-Fan.
The S/PDIF module is purchased separately.
Do not forget to connect the fan cable to the fan connector. Insufficient air flow
inside the system may damage the motherboard components. This is not a
jumper! DO NOT place jumper cap on the fan connector.
