temperature issue with voxl 2

Jetson Nano

I am facing an issue of over heating and servers or wifi not working properly. Even with out any flight , a drone that is kept open, causes the voxl 2 board to reach 60 degree Celsius very fast, with in a matter 2 - 3 minutes.
What could be the reason for the sudden temperature rise.

I am running with 2 tracking, 1 hires, 1 TOF connected to Voxl2 . along with camera, mapper, openvins, and vision servers.
The px4 is running on the external flight controller.
Also while booting itself the flight controller is showing random height as reference in QGC, after rebooting it settles, what could be the reason for this error too.
please clarify my doubts

The temperature rise is when i run the voxl-camera-server. I tried with turning off and on individual server and as soon as i turn on the camera server temperature rises up by 30 to 40 degree celsius, that is upto 88-90 degree celsius. this affects the performance

@Jetson-Nano , 60C is not an issue for embedded devices (throttling limit is around 95C, at which point the CPU will start reducing frequency to avoid overheating).

However, you mention that the temperature can reach 90C. Please note that the camera server itself most likely is not the main cause of the CPU temperature, but the consumers of the image frames may be using significant CPU.

You should identify the main causes of temperature rise by looking at output of top to see rough cpu usage of each process, but also try disabling mapper or openvins or hires image processing (if any).

Also, without any cooling, it is not a surprise that VOXL2 could overheat if its cpu / gpu load is very high. The SoC cannot run without cooling at full power. Airflow during flight usually provides significant cooling and you can manage the system load when not in flight or add cooling for stationary use cases (lack of air flow from propellers),
