Quick question: a few months ago, my GPU started making a slight buzzing noise. It only happens on certain games, and only when something is being rendered. Definitely not coil whine, it sounds like when you hold a pieced of paper or something in a fan. It's not the fans though (although there was an incident with the fan around the time this started, but I ruled that out already). I have to put my ear right next to the case to hear it when it's happening, but it's still there.
I've played probably 20 hours worth of games on it since the buzzing started, and noticed no difference in performance from before it started. I'm just paranoid that the noise is indicative of a possible failure in the future, specifically one that could harm all the other parts.
My question is basically this; should I be concerenced that whatever is causing this could hurt my whole build? Or will it be self contained if it becomes a bigger issue in the future? And should I even be worrying about this noise? I'd imagine that PC parts have safety features to stop one part from ruining another, but this is my first PC so I'm not sure.
