Fan Power Connectors: CPUFAN, SYSFAN1
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 con-
nected 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.
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 Overclocking 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
