To some extent, yes. But nobody should need to be running a notebook cooler when on battery power... when on battery power mine automatically underclocks the GPU and I configured it to underclock and undervolt the CPU as well. I'd love to do the same to the RAM, but that's just not possible without the BIOS options to do so.
