Fan Power Connectors: CPUFAN1, SYSFAN1
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.
Important
Please refer to the recommended CPU fans at Intel
®
official website or consult
the vendors for proper CPU cooling fan.
