CPU, Chassis, and Power Fan Connectors
(3-pin CPUFAN1, CHASFAN1, PWRFAN1)
The three fan connectors support cooling fans of 350mA (4.2 Watts)
or a total of 1A (12W) at +12V. Orient the fans so that the heat sink
fins allow air flow to go across the onboard heat sinks instead of the
expansion slots. The fan wiring and plug may vary depending on the
fan manufacturer. Connect the fan cable to the connector matching
the black wire to the ground pin.
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!

SMBus connector (6-1 pin SMB)
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. SMBus is a specific
implementation of an I
2
C bus, a multi-device bus that allows multiple
chips to connect to the same bus and enable each one to act as a
master by initiating data transfer.
