BUG: Windows 11 Power saver plan


Windows 11 keeps my CPU (Ryzen 7 5800X) at maximum frequency with the Power saver plan, minimum processor state is set to 99% and maximum processor state to 100%.
On Windows 10 that works as supposed, but not on 11.
So just opening Edge I noticed that CPU went up, by a lot, 64C!

After a while it only drops down to 50C, while on Windows 10 it will drop down to 36C from 43C.
When taking the attached screenshots I noticed one difference between the power plan on the two OS versions, there is something missing on 11,  "System cooling policy".
Could the reason for the power plan in question not working normally be that something else has been removed as well?

Just for info, HWMonitor 1.44 shows the same difference.
Also take note that the pump and fans cooling my CPU are controlled by the motherboard and not any software installed on Windows.
Knowing that just look at the RPM difference (615 vs 1235).

Updated from Windows 10 21H2 to Windows 11 build 22000.184 yesterday, didn't face the issue so far.

Played a game  for an hour, watched a few YouTube videos, computer was idle some minutes and the issue is back. *sigh

On build 22000.282 now, issue still exists, also seen other Ryzen users write about it.

Some more info that should be useful for pinpointing the issue.

On Windows 11 I had to switch to Balanced with the Power Mode set to Balanced and set the clock multiplier down with 1 to get the same result, Power Saver plan is still borked on 11, goes to max with browser and other stuff that normally does fine at stock frequencies.
Not quite sure why it only works on 11 when turning the multiplier down instead of using the CPU's stock value.

On Windows 10 21H1 this issue doesn't exist, not sure about 21H2 but I doubt it.

When is Microsoft/AMD going to fix this issue?
Do we really need to roll back to Windows 10 or switch to another OS for our Zen 3's to throttle up and down based on demand instead of hampering them or running full blast 24/7?

If Ryzen doesn't slow down the CPU clock,
you'll need to edit the registry yourself or use a third-party power plan.
First, if the game mode is enabled, try disabling it.

Here's what I'm testing.
If anyone wants to use it, create a system restore point in advance.

That plan looks pretty descent, how does it behave when you throw some heavy game at it?

I'm currently using Process Lasso to switch between powersaver and a custom balanced plan dependent on what I run, which also ensures that no cores are parked for multithreaded applications, but at the same time I did set a temperature limit within BIOS. 
That allows me to run Windows 11 with all it's bells and whistles including Game Mode.
Will test your profile v6 later to see how it compares, still funny that we have to sort to 3rth party/custom plans to make it work when it worked perfectly fine on Windows 10.

In most cases, a properly tuned power plan will work just fine.
*Core Park can be displayed with the following GUID.
powercfg -attributes SUB_PROCESSOR 0cc5b647-c1df-4637-891a-dec35c318583 -ATTRIB_HIDE


*The following items are required to finely control the clock.




Thanks, the attached batch scripts are really helpful, installed the plan and edited one of them to my preference to make it work on Windows 11 like it did for me on Windows 10 together with some minor improvements.
