2.1-4 CPU Fan Power Connectors: JFAN/CFAN1/SFAN1/
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 LM78 chipset on-board, you must use a specially designed
fan with speed sensor to take advantage of LM78's CPU fan control.
