I don't think you'd smell much even if things were getting hot enough to accelerate wear on the iron - after all, you don't smell wood burning when a scraper gets hot, and I don't think an iron is reaching that level for the reasons Bill mentioned.

I would be pretty surprised to see an iron get hot enough to worry about temper in planing. I wouldn't be surprised at all if the very edge of it got hot enough to affect the overall mechanisms of wear.

If you really want to know the temperature at the edge, you might be able to set up some kind of holder for a laser thermometer. They actually work quite well and usually have a peak hold feature. I think some of the better multimeters have temperature probes and a setting on the meter to display calibrated temperature - that would be easier to set up on a plane, but a more expensive system.
