III. HARDWARE SETUP 24. CPU/Chassis Cooling Fan Connectors (FAN, 3 pins) These connectors support 3-pin cooling fans of 500mA (6W) or less with a minimum of 3,500RPM. Orientate the fans so that the heatsink fins allow airflow to go across the onboard heatsink(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 connector. NOTE: The "Rotation" signal is to be used only by a specially designed fan with rotation signal. The Rotations per Minute (RPM) can be monitored using ASUS PC Probe Utility. WARNING! The CPU and/or motherboard will overheat if there is no airflow across the CPU. Damage may occur to the motherboard and/or the CPU fan if these pins are incorrectly used. These are not jumpers, thus, do not place jumper caps over these pins.

24. CPU/Chassis Cooling Fan Connectors (FAN, 3 pins)
These connectors support 3-pin cooling fans of 500mA (6W) or less with a mini-
mum of 3,500RPM. Orientate the fans so that the heatsink fins allow airflow to
go across the onboard heatsink(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 connector.
NOTE: The “Ro-
tation” signal is to be used only by a specially designed fan with rotation
signal. The Rotations per Minute (RPM) can be monitored using ASUS PC
Probe Utility.
WARNING!
The CPU and/or motherboard will overheat if there is no airflow
across the CPU.
Damage may occur to the motherboard and/or the CPU fan if
these pins are incorrectly used.
These are not jumpers, thus, do not place
jumper caps over these pins.
