2.1-5 Fan Power Connectors: JFAN1, JSFAN1, & JPFAN1
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 can use a
specially designed fan w/ speed sensor to take advantage of System Hard-
ware Monitor’s CPU fan control.
Note: Always consult vendor for proper CPU cooling fan.
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.
