    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.
