Anybody else get a very faint high pitched "buzz" a lot like a tiny nat buzzing around, when their up2 is on?

There's also a tiny clicking sound that seems to happen every second or so. It's really faint and I only noticed today whilst I was working with it (to try and fix the graphics issues) without the telly on, but took me by surprise as there's no moving parts and it's quite noticeable.

    Yes I can hear it too. Have to get real close to it. I guess it's the heat sink buzzing. I did it when I tested the speed of it and the heat sink for super hot with out a fan.

    The buzzing sound could come from a coil and if it does, it's nothing to worry about. It may be a tad annoying, but coils just tend to do that, especially cheaper ones. I can't say about the clicking sound, though. I suppose it could be the heatsink expanding/retracting with temperature-fluctuations, but I dunno; does the clicking sound still happen, if you let the board sit totally idle for, say, 5 or 10 minutes and if so, does it start to happen again when you're actually running something?
