Hardware Setup
Fan Power Connectors: CPU_FAN1, SYS_FAN1
The fan power connectors support system cooling fan with +12V. When connecting
the wire to the connectors, always take 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.

1. Please refer to the recommended CPU fans at Intel
®
official website or
consult the vendors for proper CPU cooling fan.
2. CPUFAN1 supports fan control. You can install Core Center utility (refer to
Appendix for details) that will automatically control the CPU fan speed
according to the actual CPU temperature.
