I just bought an XPS 13 9360 and returned it due to the coil whine. I've never had that issue on my Macs before so once I get refunded I'm going to buy a MBP instead.

I've been hearing about the coil whine for ages, but I've never heard it over multiple 9550s and a 9360. I'm even in an office right now surrounded by the 9550s which were supposed to be plagued by the issue. Is it that the whine is occurring at a frequency I can't hear?

my T450s has coil whine but you have to be in a dead silent room to hear it, I assume it would be the same for the Dells

It's loud enough on my 9350 I can hear it clearly over the top of music or videos playing.
