Thermal Considerations
6.1.
Available Processors
Please refer to the chapter 10/ “Technical Specifications”.
The list of processors is not complete and may be extended over the product lifetime.
6.2.
Convection Cooling
The applied cooling method provides adequate cooling of the device during operation and performs a one-way
thermal transfer to the chassis. Three sides of the KBox A-103 consist of a compact aluminum U-shaped chassis are
with cooling fins. The cooling fins provide heat dissipation during operation.
To provide sufficient heat dissipation for the cooling of the KBox A-103, never cover the
cooling fins of the chassis. Do not place any objects on the device.
6.3.
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 chapter 7.1 “System Mounting” and Figure 34).
6.4.
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 75% 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. 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.
6.5.
Third Party Components
When the KBox A-103 is extended and configured with third party components like mPCIe extension cards and hard
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 for assistance.
