4.7.5 CPU, Auxiliary and System FAN Connectors (FCPU, FAUX and
FSYS)
There are three fan connectors on this motherboard. The J39 (FCPU) is designed to support CPU fan;
the J41 (FSYS) is for system fan used and you can connect any auxiliary fan to the J40 (FAUX).
Depending on the fan manufacturer, the wiring and plug may be different. In most of the case, the red
wire is positive, while the black is ground. Connect the fan’s plug to the board taking into consideration
the polarity of the connector.
The “Sense” signal is to be used only by a specially designed fan with rotation signal. You may
use the hardware monitoring utility to monitor the Rotations per Minute (RPM) of the fan.
1. The CPU will overheat if there is no airflow across the CPU heatsink.
2. Damage may occur to the CPU fan and/or motherboard if these pins
are incorrectly used.
4.7.6 Auxiliary Temperature Sensor Connectors (TAUX)
This motherboard has one temperature sensor header. You can connect the temperature sensors
to these headers in order to monitor the temperature.The one connector without orientation
limit.
The CPU temperature can be monitored by a CPU inside thermal diode. If
your CPU does not have this feature, purchase one temperature sensor
and connect it to the Auxiliary Temperature Sensor Connector.
Onboard System Temp Sensor.
