HARDWARE INSTALLATION
2-3
2.1-4 Fan Power Connectors: J9, J12, & J6
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 this function.
Note: For fans with fan speed sensor, every rotation of the fan will send out
2 pulses. System Hardware Monitor will count and report the fan rotation
speed. This is an optional function for System Hardware Monitor.
