change the speed may be used if necessary.
2. Fan Connectors
There are two fan connectors
on the P6F94 mainboard for
the cooling fans. The
connectors support fans of
12V DC/500mAMP (6
WATT) or less. When the
system goes into sleep state,
fan should be shut down to
eliminate audible noise and
reduce power consumption. You can monitor the fan speed by way of
W83781D chip and the fan must come with a tachometer output.
