Coil whine with graphics cards is such a frustrating experience, because there is no informed consensus as to what the underlying cause truly is. Everyone has their own anecdotal reason: a) Maybe coil whine is an intrinsic factor in the manufacture of graphics cards, similar to dead pixels on displays. "Luck of the draw" when obtaining one is the only way to win. Cycle through RMAs until you get one with little to no coil whine. b) Or, it depends which company you buy from: each of Asus, EVGA, Gigabyte, MSI, Zotac et al are supposedly better or worse than the others. c) Or, it's not a problem with the GPU at all; rather, it's an indication of a poor quality power supply (PSU). I've never seen an informed analysis from an industry engineer who has a goddamn clue what they are talking about. NVIDIA could probably enlighten us all with an exact-science explanation, but that seems unlikely. My uneducated guess is that the situation is closest to option 'a' above, and that rejecting units for coil whine during quality control would drastically reduce production yield.
