2-28 Chapter 2: Hardware information
8. 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!
9. 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.
