These fan connectors support CPU/System chassis cooling fan with +12V.
When connecting wire to FAN connectors, users should pay attention
that the red wire is for the positive current and should be connected to
pin +12V, and the black wire is Ground and should be connected to pin
GND. If your mainboard has Hardware Monitor chipset on-board, you
must use a specially designed fan with speed sensor to take advantage
of this function.
For fans with speed sensors, each rotation of the fan blades will send out
2 electric pulses, by which System Hardware Monitor will work out the
fan rotation speed by counting the pulses.
NOTE 1:
Always consult vendor for proper CPU cooling fan.
NOTE 2:
CPU FAN is supported by Hardware Monitor, with a warning
will be given out to high CPU temperature.
