Maybe the temperature sensor could be off. The way i would find out is take the screws out of the bottom case, but leave the panel on. Use the computer on a flat surface (to keep the panel in place) for a bit, then once it gets that hot open up the cover and feel it. If it's really 128˚, it'll be very hot, so watch out. Personally, though, I doubt it is considering temps that high might even be hot enough to melt some of the plastic surrounding it, and it would probably trip some of the various other sensors in the computer as well.
