1.4 System Health Monitoring
Onboard Voltage Monitors
The onboard voltage monitor will continuously scan crucial voltage levels. 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
The system health monitor chip can check the RPM status of a cooling fan. The processor
and chassis fans are controlled by the BIOS Thermal Management.
Environmental Temperature Control
The thermal control sensor monitors the processor temperature in real time and will turn on the
thermal control fan whenever the processor temperature exceeds a user-defined threshold.
The overheat circuitry runs independently from the processor. Once the thermal sensor detects
that the processor temperature is too high, it will automatically turn on the thermal fans to
prevent the processor 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,
processor temperatures, voltages and fan speeds go beyond a predefined range.
