More for others reading this thread, I did notice after upgrading to Windows 11, I lost access to the System Cooling Policy under power options > advanced settings which did mean laptop cooling fan was very active whilst plugged in.
The only option available under power options > advanced settings > processor power management > was minimum processor state and maximum processor state.
So to re-add the system cooling policy, I created via notepad the following .reg document named – ‘Windows Registry Editor Version 5.00’ and added the below text.
ref file name: Windows Registry Editor Version 5.00.reg

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\94D3A615-A899-4AC5-AE2B-E4D8F634367F]
“Attributes”=dword:00000002

Then I saved the Windows Registry Editor Version 5.00.reg file to my desktop and doubled clicked the file and approved the question it asks to add the necessary reg files to allow changes to the registry.
System Cooling Policy now Available
