9. Chassis / CPU / Power Supply Fan Connectors (3-pin FAN)
These connectors support cooling fans of 500mA (6W) 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 consideration
the polarity of the this connector.
NOTES:
The “Rotation” signal is to be used only by a specially designed fan with
rotation signal.
The fans have been designed to power off after entering the sleep/soft-off mode.
This is to reduce both energy consumption and system noise.
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.

10. Wake-On-LAN Connector (3-pin WOL_CON)
The WOL_CON connector powers up the system when a wake-up packet or
signal is received from the network through the ASUS PCI-L101 LAN card.
IMPORTANT: This feature requires that the Wake-On-LAN Power Up Control is
set to Enabled (see Power Management Setup under BIOS SETUP) and that your
system has an ATX power supply with at least 720mA +5V standby power.
