Processor squeal (alien.top)

So I was thinking about repurposing and old AMD A10 motherboard and processor into a 3rd proxmox server mostly to make quorum. But when booting it up, there is a very annoying squealing sound coming from near the processor. It's definitely not a fan as I've already stopped them from spinning and the sound continued. I don't know for sure that it's from the proc as it could be some other near by component. Any ideas? I'm thinking about re-pasting the processor to see if that will help. But other than that I'm not sure. Maybe a cap is going bad?

Welcome to the world of capacitors and chokes.

Basicly: The power delivery to your CPU is the squeely bit.

[–] knook@alien.top 1 points 11 months ago

Probably inductors noise from the CPU power rails right next to the CPU. Not much you can do about it.

Does it sound like coil whine?

[–] Durz0Blint123@alien.top 1 points 11 months ago

Yeah I think so.

You sure if it's not an alarm coming from the motherboard? Does it POST properly?

[–] Durz0Blint123@alien.top 1 points 11 months ago

Oh definitely not an alarm. Too faint. And yeah, posts fine and has OS loaded. No errors anywhere. Just a little whine.
