CPU/System Fan Power Supplies
There are two fan connectors on the mainboard for the cooling fans.
The connectors support fans of 12V DC/500mAMP (six watt) or less.
When the system goes into sleep state, fans should be shut down to
eliminate audible noise and reduce power consumption. You can
monitor the fan speed by way of the VT82C686A chip (providing the
fan comes with a tachometer output).
You can monitor the fans’ RPM with the Hardware Doctor utility.
Refer to
System Environment Monitor
in Chapter 5 for details.
