Overheating shut down - Jetson Nano

I am using Jetson Nano to do real-time object detection from RTSP stream. I am using SSD-MobileNet-v2 for inference.

I have no problem running object detection from the stream but when I leave it for more than 15-20 minutes let’s say, it turns off and the heat sink is extremely hot. When I monitor system info the CPU is at about 96-97% and RAM is at about 40-50% (I did the 8GB swap).

All installations are done by following this amazing blog [url]https://jkjung-avt.github.io/[/url] by JK Jung.

Hi milos4cyf2,

Run “sudo tegrastats” from terminal to keep an eye on the temperatures and power usage. See here for documentation on the tegrastats output:

https://docs.nvidia.com/jetson/l4t/Tegra%20Linux%20Driver%20Package%20Development%20Guide/AppendixTegraStats.html#wwpID0E0SB0HA

What is running before the unit freezes? Which Micro USB power supply are you using? You might want to try one of the supplies from this post.

In the meantime, you can try putting the board into 5W mode to see if that improves the stability:

$ sudo nvpmodel -m 1

If it doesn’t freeze then, that would probably indicate a power supply issue (not delivering enough steady power).

Thanks!
Yeah, I was at 10W mode because I installed a bunch of stuff and wanted to do it quicker. When I put it at 5W it works fine, after 50 minutes it’s at ~55°C.

Seeed Studio just released ICE Tower CPU Cooling Fan for Nvidia Jetson Nano said "It can reduce the temperature of the Jetson Nano from 85℃ to 45℃. " [url]https://www.seeedstudio.com/ICE-Tower-CPU-Cooling-Fan-for-Nvidia-Jetson-Nano-p-4214.html[/url]

Hope helps
