I would suggest not trying to use it anymore though, and just go straight to the RMA process for wherever they were purchased. Or maybe post on the GN discord to see what they say (annoyingly they don't have forums or anything, just a discord and subreddit).

If this is just something that's come from somewhere else, you don't know where else this mysterious metal may have gone, and there's a potential fire risk on your hands at worst, or a mobo that could fry any cpus (or memory, etc) plugged in.

If it's indeed the issue talked about by GN, it's dead, and if it's not completely dead, it's actively dying in an irreversible way.

If it's some other, new issue, I still can't imagine plugging it back in will make anything better.

The photo is almost identical to one shown in one of the GN videos. Gonna be a bad internet denizen today though and ask that you take my word, because I really can't be arsed to try to look up specific videos and times.

If you don't take my word, thats completely understandable, but as I said, cannot be arsed with looking it up, so I'll just accept that you don't believe me.

Last year GamersNexus covered something similar. Can't remember the exact video, but I think it was in the series of videos this one comes from https://m.youtube.com/watch?v=fFNi3YNJXbY&t=0s.

Can't remember all the details, but (I think) something was causing a part of the die (I guess not near a temp sensor) to heat up way out of spec, enough to litterally melt the solder on the CPU, and have it drain out.

CPU is likely dead, and certainly not to be trusted. Is it an Asus or gigabyte motherboard? Potentially it's one that's affected and hasn't had the bios update that fixes the issue applied
