Yup. The damning thing is, when questioned about the issue, Dell representatives have always declared that the HW is working within specs. I don't recall the exact wording, something like "noise emissions level is under some required threshold" (I don't have the link at hand but I think I can rescue at least one from Dell support forum). The thing is, to me the fan noise when it turns on is less annoying than the high pitched whine. I have an old XPS 13 model (9333 I think, the battery is still going strong tho) and with the keyboard backlight turned off (I won't use it anyway) and no USB peripherals attached is dead silent. Otherwise, If I plug a mouse or an USB hub/network adapter there is the continuous whine. To be honest, I can only hear it in silent rooms in my home with window closed, in an office environment it's droned out. The whine is the only gripe I have with the HW as Debian has worked flawlessly with it.
