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 CPU and
chassis fans are controlled by the BIOS Thermal Management.
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, please provide adequate airflow to your
system.
System Resource Alert
This feature is available when used with SuperDoctor 5
®
in the Windows OS or in the Linux
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.
