After seeing Alex's post, I tried installing 410.104-0ubuntu0~18.10.1 from ppa:graphics-drivers.
Using 4.18.0-16-generic kernel.

I find that when I use Intel profile, powertop reports the nvidia card as 0% active, and the setting in Tunables shows up as Good.
However, /proc/acpi/bbswitch reports as 0000:01:00.0 ON, and the *fans* are spinning.

Turning the graphics card OFF with bbswitch, the fans stop spinning.
