Hardware Setup

Fan Power Connector: CPUFAN1, SYSFAN1, AUXFAN1

The fan power connectors support system cooling fan with +12V. When 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.

Serial Port Connector: COM2

This connector is a 16550A high speed communications port that sends/receives 16

bytes FIFOs. You can attach a serial device to it through the optional serial port

bracket.
