My fiancee has a mouse(Logitech MX Master) which has a very-high pitched coil whine, but only when you move it. It's the most infuriating thing in the universe, but apparently she can't hear it. So yes, random coil whine is about 10000x worse than fans.

So her mouse squeaks? That’s adorable!

If you google "Logitech mouse coil whine" you will see that this has affected multiple Logitech models for many, many years. They apparently have no interest in fixing this issue.
I find it funny that this post has become the second result on google when searching for this phrase now :P

Same with the Dell XPS 9560 but talk to their customer service department and they'll deny all knowledge...
I've had my top-of-the-line Dell XPS serviced(motherboard fully replaced) 3 times because of the coil whine issue, and it's not going away, and Dell said they will not replace it any more. It's one of their most expensive laptops and they can't get such a basic thing right.
Last year when I was deciding which laptop to buy for personal use I ruled out the XPS15 (partially) on coil whine (I'm 37 but thanks to never going to concerts and rarely listening to music beyond half volume I still have decent high frequency hearing).
In the end I went with a Thinkpad and having seen the issues people I know have had with the XPS15 I'm pretty glad I did.
That's not the mouse, but the CPU causing coil whine when the mouses causes the kernel to up it's CPU usage as you fly across various GUI elements.
Unless you've tested OP's fiancee's system yourself and found that to be the case, I wouldn't be so sure.
I had a Logitech G500 with awful coil whine and the opposite problem: it would stop whining when moving and start when idle. I suspect it had to do with the power saving mode that lots of mice have, where the laser power supply ramps down to dim the laser illumination after a period of no detected motion.
A lot of times I've noticed it's the USB controller. It's quite evident when you have headphone ports near USB ports.

I can be tabbed out and hear when I get into the plane in PUBG from the increase in whine. It's quite nice actually.
Not necessarily. Possible, but I had a cheap HP mouse that whined briefly when it first came out of sleep mode. Couldn't have been the computer, since it would make the same noise when the PC was turned off.
That is not the case - the mouse itself is whining, it does it even when the receiver is not plugged into anything.
