Intel Nuc Operating Temperatures

Hi all.

Just recently upgraded our home’s raspberry pi 4 powered Home Assistant server to a Intel Nuc with a 8th gen i5 processor, but seem to be having temp issues?

I also bought a Nuc (7th gen i3) for our beach house which worked perfectly with stable temps, but this new one seems to have problems with its temps.

Picture of the new 8th gen i5 Nuc:

*For those wondering, the gaps are when Home Assistant is off because of loadshedding, I live in South Africa.

I really don’t want to go through the hassle of returning the Nuc and searching for a new Nuc, because I live in the middle of nowhere. But maybe I should rather just do it while I stil can? What are your thoughts? Any advice would be appreciated.

Gen 8 i5. Not sure what the difference is?

The first picture shows my new 8th gen i5 Nuc. It has spikes going to the upper 90’s and hovered around 80 for the last few hours.

I did just update to Home Assistant 2023.10.1, I’m hoping it would maybe make a difference. Temp is currently at around 57°C

And 44 in my picture for same. So my NUC BIOS allowed throttling of power. I think I selected 17w. I might be wrong. What else is different?

I thought the 100°C spikes may be bad for the Nuc. But it is looking beter after the update.

Current temps:

Hoping it will stay in the 40s.

Might try to also set it to 17W. Thanks.

What is ventilation and external temperature? Water cooled A/C data centre or box cupboard next to the boiler?

Original enclosure, on top of table, not in sunlight and room temp is about 25°C to 30°C.

I would look into repasting it, I just redid mine and it dropped from the 90 range down to the 60-70 since it was due to be repasted, used thermal grizzly kryonaught as I use that on all my personal gear when I need to apply fresh paste. I’m using a NUC5i7RYH swapped to an Akasa Plato X7 passive case, it hosts my camera feed from my NAS and my HA vm at the moment
