FAN1 , FAN2 CPU Cooling Fan (FAN1,2)
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 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
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. 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.
