In my experience the XPS 15 7390 with the 6c12t cpu with Windows had the fan running very often. Each time a single cpu thread ran at 100% the fan turned on.
You can buy them from the manufacturer with no discrete graphics cards.
I have one with a card which is physically turned off for the same trick.
