III. INSTALLATION
9. Chassis Fan, CPU Cooling Fan, & Power Supply Fan Connectors (FANPWR)
These connectors support cooling fans of 500mAMP (6WATT) or less. Orien-
tate 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 consid-
eration the polarity of the this connector. NOTE: The “Rotation” signal is to
be used only by a specially designed fan with rotation signal.
WARNING: The CPU and/or motherboard will overheat if there is no air-
flow 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.
R
Orientate the fins so that air flow
runs across motherboard's regulators.
