    You must be signed in as an administrator to add or remove this setting in Power Options.

    Running an old laptop 24/7 on Folding, with temps getting close to Tj, max, neither using the CMD command nor dropping the power for maximum processor state would work. I changed the power plan from Balanced to High Performance and dropping the max processor state by 2% it went from 1.9 GHZ to just under 1.6 GHz. Running slower but much cooler. No Idea why changing the power plan made a difference.

    Hmm, that is odd. It should work no matter which power plan you are using.

    I agree. As soon as I change back to Balanced, regardless of the settings on that plan, up it goes to just over 1.9 GHz again and the fan ramps up.

    Hello Jaynic, and welcome to Ten Forums.

    Running the command in option 1 to add or remove the Maximum processor state power option itself will make no difference. It will only hide or show the setting without making any changes to it.

    By default, Maximum processor state is set to 100% to allow up to 100% of the CPU.

    If you have a restore point available dated before this issue happened, you could try doing a system restore using the restore point to undo and fix this.

    It may be best to post this issue in the Gaming forum area instead to troubleshoot what may be happening with the game and your system.

    Hello Again,
    Just to confirm, did you close and reopen Power Options to apply the change. It will not automatically show the change.

    If so, run the same command in an elevated PowerShell instead. I've noticed lately the add command sometimes only works in PowerShell for some unknown reason even though it shouldn't matter.
