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, 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.
1.5 ACPI Features
The Advanced Configuration and Power Interface (ACPI) specification defines a flexible and
abstract hardware interface that provides a standard way to integrate power management
features throughout a computer system, including its hardware, operating system and
application software. This enables the system to automatically turn on and off peripherals
such as CD-ROMs, network cards, hard disk drives and printers.
In addition to enabling operating system-directed power management, ACPI also provides a
generic system event mechanism for Plug and Play, and an operating system-independent
interface for configuration control. ACPI leverages the Plug and Play BIOS data structures,
while providing a processor architecture-independent implementation that is compatible with
appropriate Windows operating systems. For detailed information regarding OS support, refer
