CHAPTER 2 HARDWARE INSTALLATION

• Fan Power Connectors: CPUFAN & SYSFAN
These connectors support system cooling fan with + 12V. It supports
three pin head connector. When connecting the wire to the connec-
tor, 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.
Note: Always consult your reseller for proper CPU cooling fan.
