The new BIOS updates addressed the whine issues I had. Might have been worth checking out before just taking it back :)

EDIT: To be clear, my issues were resolved after an update back in Dec 2017: http://www.dell.com/support/home/us/en/19/Drivers/DriversDet...

"Optimize CPU loading to Improve EE noise" is specifically one of the issues that BIOS update addresses.

Wow, I'm impressed that a BIOS update can fix a coil whine. Got any background info on how they did it? Or did they just disable some core hardware feature for it?

I have no idea on the implementation, but it seems that they resolved it with 'CPU loading' optimizations: http://www.dell.com/support/home/us/en/19/Drivers/DriversDet...

Oh, that is great news. I have an XPS 13 (9350) and the whine is incredibly frustrating.
