1.4 System Health Monitoring
This section describes the health monitoring features of the motherboard. The motherboard
has an onboard System Hardware Monitoring chip that supports system health monitoring.
Onboard Voltage Monitors
An onboard voltage monitor will scan the voltages of the onboard chipset, memory, CPU,
and battery continuously. Once a voltage becomes unstable, a warning is given, or an error
message is sent to the screen. The user can adjust the voltage thresholds to define the
sensitivity of the voltage monitor.
Fan Status Monitor with Firmware Control
PC health monitoring in the BIOS can check the RPM status of the cooling fans. The onboard
CPU and chassis fans are controlled by Thermal Management. Refer to the below table for
available fan modes to choose the most appropriate one for nominal operation.
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real time and will turn on the
thermal control fan whenever the CPU temperature exceeds a user-defined threshold. The
overheat circuitry runs independently from the CPU. Once the thermal sensor detects that
the CPU temperature is too high, it will automatically turn on the thermal fans to prevent the
CPU from overheating. The onboard chassis thermal circuitry can monitor the overall system
temperature and alert the user when the chassis temperature is too high.
Note: To avoid possible system overheating, provide adequate airflow to your system.
System Resource Alert
This feature is available when used with SuperDoctor 5
environment. SuperDoctor is used to notify the user of certain system events. For example,
you can configure SuperDoctor to provide you with warnings when the system temperature,
CPU temperatures, voltages, and fan speeds go beyond a predefined range.
Fan Mode
Quiet
Use this mode to set fan speed for best power effi ciency and maximum noise reduction
Stable
Use this mode to set the fan speed for normal system cooling
Full Speed
Use this mode to set fan speed at full speed for maximum system cooling
Customize
Use this mode to manually adjust the desired PWM according to the specifi ed temperature
