1-3 PC Health Monitoring
This section describes the PC health monitoring features of the the P8SAA+.
The motherboard has an onboard System Hardware Monitor chip that sup-
ports PC health monitoring.

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/Fan Fail 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 or a fan failure occurs,
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.
