Alienware m15, way to lower CPU idle frequency when plugged in?

I have m15 r1 with i7-8750H. Currently when the laptop is plugged in the CPU keeps boosting to >3.8 Ghz at all times, even when there is no load (>98% Idle in task manager).

I want to let the CPU to drop its frequency to around 1Ghz when idle and plugged in, so that the laptop can be cooler. I tried editing power plans->minimum processor state in control panel and/or changing similar settings in AWCC with both balanced and performance plan. None of them work.

What I DON'T want to do: limit CPU max frequency, which reduces performance.

I have also noticed this with my M15 and it irritates me too! 

When this happens, if I switch to a power plan I created that eliminates turbo, the temps drop about 3 or 4C!  BUT like you said, this is not a good solution, I thought speed shift was supposed to downclock when idle? 

I also notice that if I leave it for quite some time, it will eventually downclock.  What the heck is it doing when it first powers on that it wants to burn power for nothing?
