10. CPU and system fan connectors (3-pin CPU_FAN1/2, REAR_FAN1/2,
FRNT_FAN1/2)
The fan connectors support cooling fans of 350 mA ~ 740 mA (8.88 W max.)
or a total of 2.1 A ~ 4.44 A (53.28 W 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!
11. Backplane SMBus connector (6-1 pin BPSMB1)
This connector allows you to connect SMBus (System Management Bus)
devices. Devices communicate with an SMBus host and/or other SMBus
devices using the SMBus interface.
