The onboard voltage monitor will scan these voltages continuously. Once a
voltage becomes unstable, it will give a warning or send an error message
to the screen. Users can adjust the voltage thresholds to define the sensi-
tivity of the voltage monitor.
Fan Status Monitor with Firmware/Software Speed Control
The PC health monitor can check the RPM status of the cooling fans. The
onboard fans are controlled by Thermal Management via BIOS.
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning
function in the BIOS. This allows the user to define an overheat tempera-
ture. When this temperature reaches the threshold, the CPU thermal trip
feature will be activated and it will send a signal to the Speaker LED and, at
the same time, the CPU speed will be decreased.
