SUPERSERVER
CPU Temperature/System Temperature
This feature displays current temperature readings for the CPU and the System.
The following items will be displayed for your reference only:
System Temperature
The item displays the absolute temperature as detected by the BIOS.
CPU Temperature
The item displays the level of CPU temperature (High, Medium, Low) as detected by the BIOS. The information shown in the screen is for your reference only. (See the notes below for more information on PECI and TControl.)
•CPU Temperature Setting - Low: When CPU PECI (Platform Environ- ment Control Interface) count is below or equal to
•
•
CPU Temperature Setting - Medium: When CPU PECI count is greater than TControl - 100 C but below TControl.
CPU Temperature Setting - High: When CPU PECI count is greater than TControl. (TControl<PECI Count)
Notes:
1. According to Intel's specifications, PECI and TControl are defined as follows:
•
•
PECI (Platform Environmental Control Interface): PECI is a bus interface that provides a communication channel between Intel processor/chipset components to external thermal monitoring devices. It sends readings from the Digital Thermal Sensor (DTS) located in the processor to an external device for fan control purposes. PECI replaces the thermal diode available in the older versions of processors.
TControl: TControl is a temperature reading from the Digital Thermal Sensor (DTS) in the CPU used for fan speed control mechanisms. It can be referred to as a trigger point to trigger a CPU Overheat/Fan Control alarm.
