CPUFAN,SYSFAN1~2: Fan Power Connectors
The fan power connectors support system cooling fans with +12V. If the motherboard
has a System Hardware Monitor chipset on-board, you must use a specially designed
fan with a speed sensor to take advantage of the CPU fan control. Remember to
connect all system fans. Some system fans may not connect to the motherboard and
will instead connect to the power supply directly. A system fan can be plugged into
any available system fan connector.
