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.

Important
Please refer to your processor’s official website or consult your vendor to find
recommended CPU heatsink.
The CPUFAN and SYSFAN1 support Smart Fan Control with liner mode. The
Command Center utility can be installed to automatically control the fan speeds
according to the CPU’s and system’s temperature.
If there are not enough ports on the motherboard to connect all system fans,
adapters are available to connect a fan directly to a power supply.
Before first boot up, ensure that there are no cables impeding any fan blades.
