Fan Power Connectors: CPUFAN1/CHSFAN1/PWRFAN1
The CPUFAN1 (processor fan), CHSFAN1 (system fan) and PWRFAN1
(power 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 designed fan
with speed sensor to take advantage of the CPU fan control.
Note:
1. Always consult the vendor for proper CPU cooling fan.
2. CPU Fan supports the fan control. You can install the PC Alert
utility that will automatically control the CPU Fan speed accord-
ing to the actual CPU temperature.
