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?
