Fan Power Connector: CPU_FAN1, SYS_FAN1/2, FRONT_FAN1
The fan power connectors support system cooling fan with +12V. W hen connecting
the wire to the connectors, always note that the red wire is the positive and should
be connected to the +12V; the black wire is Ground and should be connected to GND.
If the mainboard has a System Hardware Monitor chipset onboard, you must use a
specially designed fan with speed sensor to take advantage of the CPU fan control.
Important
1. Please refer to the recommended CPU fans at processor’s official website
or consult the vendors for proper CPU cooling fan.
2. Users are suggested to enter the BIOS Setup Utility to set up the Smart Fan
Control function.
