24 ASUS MEW-AM User’s Manual
13) CPU Fan Connectors (3-pin CPU_FAN)
This connector supports a cooling fan of 350mA (4.2 Watts) 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 consid-
eration the polarity of the connector.
NOTE: The “Rotation” signal cannot be monitored on this motherboard.
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.
