How does any shielding around the machine protect against anything related to CPU frequency, from a scientific standpoint? If I don't turn off "Allow nap" in the Shark "Processor" systeem preferences on my G5, as soon as I start a cpu intensive game (or if I e.g. drag around large objects in a Keynote presentation), the machine starts emits some kind of chirping noise. I don't know what kind of stuff can be emitted other than noise, but there definitely are parts of my machine which appear to react in an externally discernible way to cpu power consumption changes (or at least to the rate at which it changes).
