As there were recent LED updates pushed to the ROS repo, I decided to check the theory and executed a full stack with LED node, which led me to the following numbers in just 5 minutes:
However, there was another observation. In the previous message, I didn't use cameras. And when I added a couple of camera views in RViz, there was a temperature spike in the WiFi thermal zone.
I could reach 66-67 degrees. However, it never jumped above this point. So, it seems like the problem is more complicated. LEDs are still probably the main failure point. But I don't believe they cause overheating in isolation. When I shut down the ROS stack, LEDs remained active (bug). But the temperature dropped to 57-58 degrees as well. So, it seems like cameras + LEADs in conjunction cause the overheating.
Update: after a couple of hours of running the full stack with active cameras but w/o LEDs, I still reached the high temp in a WiFi zone (70-71 degrees). So it seems like it's just a matter of time to come to the red zone with active camera streams.
