4.
CPU, System, and PCI fan connectors (3-pin CPU_FAN,
SYSTEM_FAN, PCI_FAN)
The fan connectors support a CPU fan, a system fan, and PCI fan at
+12V. Orient the fans properly to 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.
Figure 2-28
CPU, System, and PCI Fan Connectors
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!

Floppy disk drive connector (34-1 pin FLOPPY)
This connector supports the provided floppy drive ribbon cable. After
connecting one end to the motherboard, connect the other end to the
