This connector supports the provided floppy drive ribbon cable. After connect-
ing the single end to the board, connect the two plugs on the other end to the
floppy drives. (Pin 5 is removed to prevent inserting in the wrong orienta-
tion when using ribbon cables with pin 5 plugged).

11) Power Supply, CPU, and Chassis Fan Connectors
(3-pin PS_FAN, CPU_FAN, DUCT_FAN)
These connectors support cooling fans of 350mA (4.2 Watts) or less. Orientate
the fans so that the heat sink fins allow airflow to go across the onboard heat
sink(s) instead of the expansion slots. Depending on the fan manufacturer, the
wiring and plug may be different. The red wire should be positive, while the
black should be ground. Connect the fan’s plug to the board taking into consid-
eration the polarity of the connector.
WARNING! The CPU and/or motherboard will overheat if there is no airflow
across the CPU and onboard heatsinks. Damage may occur to the motherboard
and/or the CPU fan if these pins are incorrectly used. These are not jumpers,
do not place jumper caps over these pins.
