Ever since Apple released the "fan fix" update for OS X, my Rev. A PowerBook's fan is almost constantly on. If I have other noise in the room like a TV show or music it's not an issue, but if the room is quiet it's really quite noisy (I've stopped taking it to any libraries for this reason). Now, granted, it does run a lot cooler, but the fan noise is almost as annoying as the heat. My question is: Is there a way to change the fan behavior back and forth or whichever? Maybe through the terminal?
