Onboard Voltage Monitors
The onboard voltage monitor will continuously scan crucial voltage levels. 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 sensitivity of the voltage monitor. Real time readings
of these voltage levels are all displayed in the BIOS.
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 BIOS Thermal Management through the back panel. Refer
to the below table for available fan modes to choose the most appropriate one for nominal
operation.
Fan Mode
Full Speed
Use this mode to set fan speed at full speed for maximum system cooling
Standard
Use this mode to set fan speed for normal system cooling
Heavy I/O
Use this mode to set fan speed for higher PCI-E add-on card area cooling
Optimal
Use this mode to set fan speed for normal PCI-E add-on card area cooling
PUE2
Use this mode to set fan speed for best power effi ciency and maximum noise reduction
Environmental Temperature Control
System Health sensors monitor temperatures and voltage settings of onboard processors
and the system in real time via the IPMI interface. Whenever the temperature of the CPU or
the system exceeds a user-defined threshold, system/CPU cooling fans will be turned on to
prevent the CPU or the system from overheating
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.
