Does this fan actually provide a better absolute heat transfer rate? I think if it's 30% more efficient, that probably just means the fan itself consumes that much less power for a given heat radiating capacity. Maybe it'll be a bit smaller or a lot quieter or something, but I don't see it "revolutionizing" anything.
