Not sure what you mean here. In general, when a car slows down, the total amount of heat generated (converted from kinetic energy) does not have much to do with pad contact area or size. What do you mean by "heat building up better"?
If you have larger pads, they will initially experience less of a temperature rise since they have more mass. Is that what you mean? If it is, that is probably not all that meaningful during extended operation as the mass of the pads will always be significantly smaller than the mass of the rotors, and if your rotors are really cooking, the mass/size of your pads doesn't matter all that much--rest assured they are cooking as well for most intents and purposes. You would have to have gigantic pads to make a significant difference.
