I'm getting what sounds like coil whine when I overclock my usb device. Default is 250, and high pitched whine is barely audible at 500, more noticeable at 1000. Bear in mind my PC is silent and the noise is barely there, but it's still pretty weird. It's definitely coming from the device itself. Anyway, I've left it at 1000 for a few hours with no noticeable ill effects, but it's still a bit weird.
