One difference is that he is only running 1x 720P camera, I have 2x 4K cameras plus 2x 1080P cameras.
It is odd though that the temp goes up so much even though the CPU load is still low. I don’t know what else to do
Take this with a grain of salt, as you can find anything on Google (even the wrong answer to a question)
https://stackoverflow.com/questions/60104698/how-do-i-monitor-the-amount-of-simd-instruction-usage
Looks like top/htop don’t show avx or other accelerated functions. So your CPU is probably heating up from avx media decoding/transcoding and not showing on top/htop
The simplest way to test it all is one by one stopping the docker containers and putting them back up. Then you can see which one is putting your CPU to that much stress. Although I can imagine that transcoding / decoding all those streams without hardware acceleration is going to be the one causing this.
if you are using docker with many containers i suggest you this: https://github.com/bcicen/ctop
so you can see who is using CPU among all containers.
BTW i have a NUC8i5 and is at 55 °C when used ( i use it as a regular pc ) and near 40 °C over night with only containers usage.
Tamb at 22 °C.
This is much more like what should be expected…
@sparkydave, you may have some setup issues with motioneye, not making use of the GPU or the hardware CODEC of the cpu for transcoding. I don’t use motioneye but I transcode 16 cams 24/7 and never exceed 56C even when doing a bunch of other things and loading my CPU upwards of 50%. I really need to abuse it with overclocking stress tools/benchmarks to get anywhere close to 85C. Either that or you have failed hardware…
Thanks. I’ll play with some MotionEye settings and see what difference it makes

@rafale77 @sparkydave I have googled what is this frontend process, and found few threads that report to disable secure boot. Had disabled, and result are great with enabled turbo boost, when zoneminder is detecting objects, maybe some short spike to 85C, when detecting and recording on motion:

That is a little more reassuring though I don’t really know why secure boot would cause zone minder to do this. Hmmm interesting… Thanks for reporting.
Thank you for explanantion, because this pushed me to investigate further! I think NUC runs now as it should be with turbo, around 50C or 60C on big loads.
I disabled secure boot yesterday and monitored CPU temp for a while, still getting peaks up over 86C and currently sitting on 76C while relatively idle other than MotionEye. Yet to work out a way to get MotionEye to not cause such a temperature rise…
A little update on this which seems to raise more questions than answers…
A couple of days ago I changed the folder location that the MotionEye addon was to save the video files, then changed it back to the original folder location, so in effect no net change. However this caused my NUC to start running at normal (~35C) CPU temperature…why? how?
Anyway I rebooted the NUC today and now it’s back to running at high temps again… something very strange with the way this addon affects the CPU temp
Did you ever solved this?
No. I ended up buying a stand alone NVR to record my CCTV cameras and stopped using MotionEye.
I have a NUC with the same problem. I have been looking for watercooling solutions but there are non. I only found this:
A custom made watercooling system. But the guys from the video do not respond to my emails. This is exactly what i need. With the setup in the video you could run the NUC on 100% cpu 24/7 i guess.
I think you will find the issue is not actually that the NUC getting getting hot but that it is reporting a high temp for some reason.
I have recently found the same issue with another add-on, QBittorrent, which sends the NUC CPU temp to 100C as soon as I start the add-on despite it just being idle… and I’m talking about an i7 NUC with 16GB RAM. The CPU usage % doesn’t go up, only the reported CPU temp. The problem is that reported temp then sets the fan to max speed etc.
My nuc i7 is around 30 to 70 degrees depending on the cpu load. With frigate running 5 cameras it’s around 20 to 30% cpu load. (Using Google coral for detection). I guess the temps are pretty accurate though
For me (why I started the thread) it was a case of a very low ~2% CPU load NUC suddenly getting reporting crazy hot when running certain add-ons despite the CPU load staying low.
Without those add-ons running (but still running a heap of others) it sits at about 1% CPU load and 38C CPU temp.
