CHAPTER 2 HARDWARE INSTALLATION

2.1-4 Fan Power Connectors: CFAN1/CFAN2/CSFAN1/
PSFAN1
These connectors support system cooling fan with +12V. It supports three
pin head connector. When connecting the wire to the connector, 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 your
mainboard has System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of the CPU fan
speed monitor feature.

Note: There are four fan connectors provided by this mainboard. But the
System Hardware Monitor can only monitor up to three fans, so the
PSFAN1 is not supported. For fans with speed sensor, every rotation
of the fan will send out 2 pulses. System Hardware monitor will count
and report the fan rotation speed.
