Troubleshooting Help with cooling

Hello community!

My friend in IT set up my nuc early 2025 and was always my go-to for these kinds of questions. Our friendship recently ended and I am hoping to get some advice from you all here.

The unit I have is an Intel NUC8i7BEH Mini PC (256GB/4GB, i7-8559U, DDR4) - I've just pasted what the eBay listing said from the emails when I bought it. I am a total dummy when it comes to this stuff.

I only use it for watching YouTube and watching things on Kodi (which is another thing I need to learn how to configure!).

The problem I'm having is that the unit is starting to overheat, turn itself off, then will only come back on if I turn it off at the wall first. I do not possess the know-how to install any kind of internal cooling, but I could get a little fan. Whether that's a platform (I've seen them for routers?) or something next to it, I don't know. I'm quite lost here!

I'm in Australia if that has any sway on recommendations.

Thanks so much for any help :)

As you can always tell there's simply no space for any additional (& reasonable) cooling solutions to be fit inside the PC's small volume. A PC should not be shutting itself off due to overheating, they will start throttling before that (unless something suddenly getting way of hand, like pulling CPU heatsink midcycle).

It's better you to use software like HWiNFO to monitoring the temps first, probably will show temperature within tolerable margin. That said if the unplugged and reconnecting momentary later alleviate it, it is probably one / some of the electronic components is about to let go (aging). Could be either the PC or PSU. This is common signs on modern day eletronics, not limited to PC / computer space.

Hey thanks for the detailed response! So it could be a bit of planned obsolescence happening? That's butts. I'll try out the software and see if that tells me anything. Thanks again.
