Fan Power Connectors: CPUFAN, SYSFAN1, SYSFAN2
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 on-board, you must use a
specially designed fan with speed sensor to take advantage of the CPU fan control.
CPUFAN/ SYSFAN2
Important
• Please refer to the recommended CPU fans at processor's official website or consult
the vendors for proper CPU cooling fan.
• CPUFAN supports fan control. You can install Control Center utility that will
automatically control the CPU fan speed according to the actual CPU temperature.
• Fan cooler set with 3 or 4 pins power connector are both available for CPUFAN.
Chassis Intrusion Connector: JCI1
This connector connects to the chassis intrusion switch cable. If the chassis is opened,
the chassis intrusion mechanism will be activated. The system will record this status
