Fan Power Connectors: Cfan1/Sfan1/Nbfan1 - MSI KT4 Ultra User Manual

Fan Power Connectors: CFAN1/SFAN1/NBFAN1

The CFAN1 (processor fan), SFAN1 (system fan) and NBFAN1
(NorthBridge fan) support system cooling fan with +12V. It supports three-
pin head connector. When connecting the wire to the connectors, 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 the mainboard has
a System Hardware Monitor chipset on-board, you must use a specially de-
signed fan with speed sensor to take advantage of the CPU fan control.
MSI Reminds You...
1. Always consult the vendors for proper CPU cooling fan.
2. CFAN supports the fan control. You can install the PC Alert
utility that will automatically control the CPU fan speed ac-
cording to the actual CPU temperature.
