There's no need to overthink this. MOS already showed that Kryptonians have an advanced physiology compared to humans (further enhanced by Solar Power). This interpretation of Kryptonians lends itself easily to lung capacity as a way of utilizing freeze breath. That is, Clark can take in large amounts of air that humans couldn't, and then expel colder air.
Jesus H. Christ guys...srsly, how is Freeze Breath any cheesier than fireballs from his eyeballs?
