I'm well aware of the other thread - it's a circlejerk. The point is that people don't know how to properly troubleshoot.
Suggesting that the old mini didn't do it and the new mini does do it, and therefore the new mini is the "issue"... is a textbook example of poor troubleshooting. It would certainly be a relevant data point, but if that's where it ends, you haven't ascertained anything. And that's my whole freaking point. It's not that I think people hearing a sound is "make believe"... it's that they are probably attributing it to the wrong device.
LOL, what forum do you think you're on?
Haha, re the forum. Well, I have coil whine on several of my homebuilt PCs as high end GPUs are pretty notorious for it at higher frame rates. I personally am fairly used to it and troubleshooting it and I can say that my 2012 on a sine wave power supply does NOT produce coil whine but the 2018 does. All other electronics off and unplugged. Something is different in (at least some) of the Mac 2018s, or else 2014/12 had the issue and people just didn't realize what they were hearing because coil whine is all around us.
