5. CPU, Power and Chassis Fan Connectors
(3-pin CPU_FAN, PWR_FAN, CHA_FAN)
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.
6. Serial Port 2 connector (10-1 pin COM2)
This connector accommodates a serial port using a serial port bracket.
Connect the bracket cable to this connector then install the bracket into
a slot opening at the back of the system chassis.
Do not forget to connect the fan cables to the fan connectors. Lack of
sufficient air flow within the system may damage the motherboard
components. These are not jumpers! DO NOT place jumper caps on
the fan connectors!
The serial port bracket is purchased separately.
