Installation and BIOS Setup
and CPU run normally as configured in the BIOS. The fans may adjust to a faster speed
depending on the Fan Speed Control settings.
User Intervention
: No action is required. However, consider checking the CPU fans and
chassis ventilation for blockage.
•
High
—The processor is running hot. This is a caution level, because the CPU temperature
tolerance has been reached (or has been exceeded) and may activate an overheat alarm:
–
Default Alarm
—The Overheat LED and system buzzer activate if the High condition
continues for some time after it is reached. The CPU fan runs at full speed to bring
down the CPU temperature. If the CPU temperature still increases even with the CPU
fan running at full speed, the system buzzer activates and the Overheat LED turns on.
–
Early Alarm
—The Overheat LED and system buzzer are activated exactly when the
High level is reached. The CPU fan runs at full speed to bring down the CPU
temperature.
Caution
In both the alarms above, take immediate action as described below.
Refer to the
section to modify the above alarm settings.
User Intervention
: If the system buzzer and Overheat LED has activated, take action
immediately by checking the system fans, chassis ventilation, and room temperature to
correct any problems.
Note
The system may shut down if it continues for a long period to prevent damage
to the CPU.
Note
In its newer processors, Intel has upgraded the CPU thermal technology that
reports absolute temperatures (Celsius/Fahrenheit) to a more advanced feature. The
basic concept is that each CPU has unique embedded temperature information that
the motherboard can read. This temperature threshold or temperature tolerance is
assigned at the factory and is the baseline by which the motherboard takes action
during different CPU temperature conditions (for example, increasing CPU fan
speed, triggering the overheat alarm, etc.). Because CPUs can have different
temperature tolerances, the installed CPU now can send its temperature tolerance to
the motherboard, resulting in better CPU thermal management.

management, refer to the Intel Web site at

Fan Speed Control Modes
Use this option to decide how the system controls the speeds of the onboard fans. The CPU
temperature and fan speed are correlative. When the CPU on-die temperature increases, the fan
speed also increases for effective system cooling.
