1.4 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 via SIO.
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 be sure to provide adequate air-
flow 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.
