2.1-4 Fan Power Connectors: CPUFAN/PSFAN/SYSFAN

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.

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.
