Bingo. That is your problem. Intel CPUs run much hotter when all of the low power C states are disabled.
This can be dependent on the power plan settings. You can try different power plans and watch the C States window to see if the C states start working.
If you open up the entire C States window, on the right hand side is a feature that can try to fix these C state issues.

Check the C States - AC box, select the Off radio button and press Apply. Do the same thing again but this time after you check the C States - AC box, select the On radio button and press Apply again. This resets some of the C state related settings within your Windows power plan.
If you still do not have any idle C state activity being reported, check your BIOS. Enable the C states in the BIOS if you have this option available.
I remember now that some manufacturers were deliberately disabling all of the C states. This is a really dumb thing to be doing to a laptop. Disabling the C states also disables the maximum turbo multipliers so you end up with both a hotter CPU and a slower running CPU when lightly loaded. Dumb and dumb.
