CP6003-SA
6.
Thermal Considerations
The following chapters provide system integrators with the necessary information to satisfy
thermal and airflow requirements when implementing CP6003-SA applications.
6.1
Board Internal Thermal Monitoring
To ensure optimal operation and long-term reliability of the CP6003-SA, all onboard compo-
nents must remain within the maximum temperature specifications. The most critical compo-
nents on the CP6003-SA are the processor and the chipset. Operating the CP6003-SA above
the maximum operating limits will result in permanent damage to the board. To ensure function-
ality at the maximum temperature, the IPMI controller supports several temperature monitoring
and control features.
The CP6003-SA includes several temperature sensors to measure the onboard temperature
values:
• Thermal sensors integrated in the processor
• Thermal sensor integrated in the chipset
• Onboard temperature sensor Temp1 (see Figure 1-6 for its placement)
The onboard temperature sensor Temp1 is accessible via the IPMI controller. For information
on the temperature sensors integrated in the CPU and the chipset, refer to Chapter 6-2 and
Chapter 6-3.
6.2
Processor Thermal Monitoring
To allow optimal operation and long-term reliability of the CP6003-SA, the 2
Core™ i7/i5 processor must remain within the maximum die temperature specifications. The
maximum operating temperature for the processor die is 100°C.
nd
The 2
generation Intel® Core™ i7/i5 processor uses the Adaptive Thermal Monitor feature to
protect the processor from overheating and includes the following on-die temperature sensors:
• One Digital Thermal Sensor (DTS) for monitoring each processor core
• One Digital Thermal Sensor (DTS) for monitoring the graphics core
• One Digital Thermal Sensor (DTS) for monitoring the die temperature
• Catastrophic Cooling Failure Sensor (THERMTRIP#)
These sensors are integrated in the processor and work without any interoperability of the IPMI
Controller, the uEFI BIOS or the software application. Thermal Control Circuit allows the pro-
cessor to maintain a safe operating temperature without the need for special software drivers
or interrupt handling routines.
6.2.1
Digital Thermal Sensor (DTS)
nd
The 2
generation Intel® Core™ i7/i5 processor includes up to six on-die Digital Thermal Sen-
sors (DTS), up to four for the processor cores, one for the graphics core and one for the pack-
age die. They can be read via an internal register of the processor. The temperature returned
by the Digital Thermal Sensor will always be at or below the maximum operating temperature
(100°C). Via the Digital Thermal Sensors, the uEFI BIOS, the IPMI controller or the application
software can measure the processor die temperature.
