Again, I don't understand how you got your reading. If something is the function of something else that means that the function is singular, not that the function only takes a singular argument. Obviously there are more things that are a function of heat than just clock speed so the op was wrong in that sense. That's the sort of mistake I make in revision all the time so I overlooked it. But even taking it literally it doesn't actually hurt the point the op was trying to make.
