I kinda thought CPU throttling was a good thing as it prevents overheating damage so not something you want to disable. But you should not be seeing any overheating on a new Dell XPS with just playing audio. So not sure what to make of that message.

I likely am going out on a limb here, but, conclusion based on antidotal information and my own individual experience with Dell XPS's .... is there still an option to return the Dell and get a machine built for purpose?
