Maximum Temperatures
The maximum system ambient temperature depends mostly on the power consumption of
the processor and the chipset.
For the temperature evaluation a specialised tool from Intel
®
was used to set the processor to a defined workload.
Depending on the power consumption one or more cores were set to 70% workload. This includes the graphics core.
The tool also handles the usage of the "Turbo Mode" of certain processor types.
The processor utilisation depends highly on the software used. Software using multicore
feature will run on several cores whereas standard software will only utilise one core.

Processor Thermal Monitoring
The processor used with the KBox A-203-sXAL4 system provides internal thermal monitoring. Every core of the
processor comprises a temperature sensor.
To allow an optimal operation and long-term reliability, the processor must operate in the specified temperature
range. To avoid overheating the processor performs an automatic thermal management, which intends to keep the
processor temperature below the highest value of the temperature range. This behavior is a CPU standard feature.
5.8.
Processor Thermal Trip Feature
The Processor Thermal Trip feature protects the processor from catastrophic overheating. The Thermal Trip Sensor
threshold is set well above the normal operating temperature to ensure that there are no false trips. When triggered,
the processor will stop all executions. This behavior cannot be altered. Once activated, the event remains latched
until power is cycled.
