When the speakers are at any volume, including muted, the right one will make buzzing noises when the SSD is actively doing something. This sounds like interference to me and it's pretty annoying in a quiet room. This seems like a manufacturing issues to me and doing any kind of reset hasn't helped. On a potentially related note, this rMBP (15" maxed out) seems to be having some pretty bad heat issues and is hot to the touch when there isn't much utilization. Do you suggest I get this replaced? It would suck to see it go considering my screen looks pretty damn good with no noticeable defects.
