I have a little fanless mini PC that runs various stuff around my house, including homeassistant. The case is basically a big heat sink.

It started crashing during backups.

The solution was to stick a fan on it. :( This is literally a box _designed to not need a fan_. And yet. It now has a fan and has been stable for months. And it's not even in a closet - it's wall-mounted with lots of available air around it.

I'm guessing it's the HDD that's failing. Had such mysterious failures with my NVR (the Cloud Key thingie) from UniFi. Turns out, HDDs don't like operating in 60+ degree Celsius heat all the time - but SSDs don't mind, so fortunately the fix was just to swap the drive for a solid state one.

I think it was the DRAM on mine, oddly. It already uses an nvme ssd. Could have been the CPU, of course - the error was manifesting as memory corruption but that could well have been happening during read or write.
