CHAPTER 2	HARDWARE INSTALLATION

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.

CFAN1 : CPU Fan

SFAN1 : System(Chassis) Fan

For fans with fan speed sensor, every rotation of the fan will send out 2 pulses. LM78 will count and report the fan rotation speed.

Note: 1. CFAN1/SFAN1/PSFAN1 are the CPU, Power and Chassis Cooling Fan Speed Connector (reserved for LM78 System Hardware Monitor Option.)

2.Always consult vendor for proper CPU cooling fan.
