2.11 Thermal Considerations
This board features a thermal protection circuit in the processor voltage regulator area.
This circuit protects the processor voltage regulator from overheating and damaging
the board. The thermal protection circuit in the processor voltage regulator sensor is
triggered at approximately 120
o
C. This trigger will cause the processor to enter a
throttling mode (slowing down the processor if it exceeds its maximum operating
temperature) and allow the processor voltage regulator to cool down.

INTEGRATOR’S NOTE
Use a processor heatsink that provides omni-directional airflow to maintain required
airflow across the processor voltage regulator area.
CAUTION
When using BIOS Setup program options to increase processor voltage and frequency
above the supported ranges, the temperature in the processor voltage regulator area
will rise. This area of the board will require increased airflow. Direct airflow over the
processor voltage regulator is crucial to preventing throttling and keeping the
processor voltage regulator area cool. This is particularly important when using liquid
cooling.
All responsibility for determining the adequacy of any thermal or system design
remains solely with the reader. Intel makes no warranties or representations that
merely following the instructions presented in this document will result in a system
with adequate thermal performance.
Figure 23 shows the locations of the localized high temperature zones.
