7. FAN1 , FAN2 , FAN3 CPU Cooling Fan (FAN/PWR)
These connectors support cooling fans of 500mAmp
(6Watt) or less. 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 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 flowing across the CPU and onboard heatsinks.
Damage may occur to the motherboard and/or the CPU
fan if there pins are incorrectly used. These are not
jumpers, do not place jumper caps over these pins.
