11. 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
floppy drive. (Pin 5 is removed to prevent incorrect insertion when using
ribbon cables with pin 5 plug).

12. Fan connectors (3-pin PWRFAN1, CPUFAN1, CHASFAN1)
The 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!
