Thermal Considerations
The following chapters provide system integrators with the necessary information to satisfy
thermal and airflow requirements when implementing CP3002-RC/CP3002-RA applications.
The CP3002-RC is a rugged, conductive-cooled version with a heat spreader.
The CP3002-RA is a rugged, air-cooled version with a front panel and a heat sink for forced
airflow cooling.

Board Internal Thermal Monitoring
To ensure optimal operation and long-term reliability of the CP3002-RC/CP3002-RA, all on-
board components must remain within the maximum temperature specifications. The most crit-
ical component on the CP3002-RC/CP3002-RA is the processor. Operating the CP3002-RC/
CP3002-RA above the maximum operating limits will result in permanent damage to the board.
The board includes three integrated temperature sensors to measure the processor and the
chipset temperature:
• Two thermal sensors integrated in the processor
• One thermal sensor integrated in the chipset

Processor Thermal Monitoring
To allow optimal operation and long-term reliability of the CP3002-RC/CP3002-RA, the Intel®
Core™ i7 processor must remain within the maximum die temperature specifications. The max-
imum die temperature for Intel® Core™ i7-610E and i7-620LE multi-chip processors is as fol-
lows:
• Processor die:
• Graphics and memory controller die:
The Intel® Core™ i7 processor uses the Adaptive Thermal Monitor feature to protect the pro-
cessor from overheating and includes the following on-die temperature sensors:
• Two Digital Thermal Sensors (DTS) for the processor cores
• One Digital Thermal Sensor (DTS) for the graphics controller and the memory controller
• Catastrophic Cooling Failure Sensor (THERMTRIP#)
These sensors are integrated in the processor and work without any interoperability of the uEFI
BIOS or the software application. Enabling the Thermal Control Circuit in the uEFI BIOS allows
the processor to maintain a safe operating temperature without the need for special software
drivers or interrupt handling routines.
6.2.1
Digital Thermal Sensor (DTS)
The Intel® Core™ i7 processor includes three on-die Digital Thermal Sensors (DTS), two for
the processor cores and one for the graphics controller and the memory controller. They can
be read via an internal register of the processor. The temperature returned by the Digital Ther-
mal Sensor will always be at or below the maximum operating temperature. Via the Digital
Thermal Sensors, the uEFI BIOS or the application software can measure the processor die
temperature.
