5. CPU and Chassis fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN1, 4-pin
CHA_FAN2)
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. They are not jumpers! DO NOT
place jumper caps on the fan connectors.
6. Serial port connectors (10-1 pin COM1)
The connector is for a serial (COM) port. Connect the serial port module cable to the
connector, then install the module to a slot opening at the back of the system chassis.
The serial port bracket (COM1) is purchased separately.
The CPU_FAN connector supports a CPU fan of maximum 2A (24 W) fan power.
