7. FAN1 , FAN2 CPU Cooling Fan (JFAN1,2)
These connectors support cooling fans of 500mAmp
(6Watt) 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 this connector.

NOTE :
The "Rotation" signal is to be used only by a specially de-
signed fan with rotation signal.
WARNING :
The CPU and/or motherboard will overheat if there is no air
flowing across the CPU and onboard heatsinks. Dam-
age 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.
