Not a dumb question at all. (There are no dumb questions, in fact. Just varying degrees of patience in answering them.)

A 1-degree difference might matter if you were trying to eek out every last second of operating time before the KX3's firmware drops power from 10-12 watts down to 5 watts (or some other metric).

For the vast majority of KX3 users, the factory-provided "slim" heat sink is entirely adequate, and an extra degree C isn't really relevant. Of 6000+ radios shipped, only a few hundred have felt compelled to add larger heat sinks. That's a good thing, since we designed the rig to be compact and lightweight.
