3.8.2 Midboard Connectors

1) Chassis & CPU Fan Connectors (3-pin CHASIS_, CPU_FAN)

These connectors support cooling fans of 500mA (6 Watts) 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 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 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.
