ive done this and got the t-shirt it does absolutly nothing it still gets as hot as 4-cores so i don`t think it even saves any power.
why would you want to shut down cores?
Was just interested in the fact that i could. A quad core was kinda overkill or me but was cheap so i went with it. Mainly just want to see how i can lower temps and conserve energy.
I did slightly test it myself and yeah it pretty much didn't do much. I my temps stayed the same but my power consumption went from 117W with 4cores at full load to 88W with 3 cores at full load.
