3.4 Thermal
The ambient operating temperature range for the motherboard is 0 - 55°C but the selection of
processor and heatsink (or fansink) can reduce the system operating range. Intel Celeron
processors have a minimum operating temperature of 5°C. The processor and fansink combinations
normally supplied as standard with the motherboards are tested using software designed to cause
maximum power dissipation in the processor. This testing is done in an environmental test chamber
with forced-air circulation. The maximum operating temperature of the supplied processor and
fansink combination is specified in the Endura Processor Support document, which can be found in
the motherboard section of the RadiSys web site.
Always test the final system configuration to determine if the operating temperature range
limits for the motherboard and processor are being met. Failure to do so can lead to
motherboard or processor damage and/or shortened life.
Intel Celeron processors have a minimum operating temperature of 5°C. Refer to the
relevant Intel processor datasheet for the maximum operating temperature.
