especially since the machine it pretty quiet apart from the squeal. I'm seriously disappointed that my first build has ended up this way. It's driving me crazy and get's stuck in my ear/head to the point I can hear it for a while after I leave the room or turn the PC off. It doesn't sound anything like examples of coil whine I've heard on Youtube, it's far too faint if that's the right word. It's exactly like that effect you hear in films after there's been an explosion and the character is supposed to have gone deaf for a few seconds if that makes sense, a really high 'eeeeeeeee'. So I build my first PC a few days ago and it makes a REALLY high pitched noise all the time, no matter what I'm doing, browsing files, checking Twitter or gaming.
