Minimum System Clearance
To provide a maximum of airflow through and around the box, minimum distances to
surrounding parts must be observed (please refer to the subsection 7.2 “Control Cabinet
Mounting” )
Maximum Temperatures
The maximum system ambient temperature depends mostly on the power
consumption of the processor, chipset and third party components:
Configurations with HDDs are limited to 50°C maximum ambient
temperature.
Configurations with wireless components (LTE, WiFi) are limited to
60°C ambient temperature.
The processor utilization depends highly on the software used.
Software using multicore feature will run on several cores whereas
standard software will only utilise one core. In this case the
processor will use the "Turbo Mode" to increase the clock for the core
with the highest workload, as long as the temperature is within
limits.

Third Party Components
When the KBox C-103-NGSF is extended and configured with third party components like
PCIe extension cards and drives (HDD or SSD), it has to be taken into account that the
air temperature inside the system is higher than the ambient temperature. An
approximately internal temperature rise is given.
6.6.
Processor Thermal Monitoring
The processor used with the KBox C-103-NGSF 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.
6.7.
Processor Thermal Trip Feature
The Processor Thermal Trip feature protects the processor from catastrophic overheating.
The Thermal Trip Tensor threshold is set well above the normal operating temperature to
ensure that there are no false trips. The processor will stop all executions when the
junction temperature exceeds approximately 125°C. This event will be indicated by the
red blinking "Thermal" LED on the front panel. This behavior cannot be altered. Once
activated, the event remains latched until power is cycled.
