14. CPU cooling fan connector (FAN)
This connector supports a CPU cooling fan of 500mAMP (6WATT) or
less. Orientate the fan 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 consideration
the polarity of the this 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.
15. IrDA-compliant infrared module connector (IR)
This connector supports the optional wireless transmitting and
receiving infrared module. This module mounts to a small opening on
system cases that support this feature. You must also configure UART
2 Use Infrared in Chipset Features Setup to select whether UART2 is
directed for use with COM2 or IrDA. When IrDA is selected in BIOS,
COM2 will be disabled. Use the five pins as shown on the Back View
and connect a ribbon cable from the module to the motherboard
according to the pin definitions.
