8. CPU Fan Power Lead (3-pin FAN1)
These connectors support cooling fans of 500mA (6W) or less. Orient the fans
so that the heatsink fins allow airflow to go across the onboard heatsink 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 consideration the polar-
ity of the this connector.
