Now before you ask me why I asked this, I just want to say that I recently began using Cyclops Cap and Fencing Jacket in T3 LD just to practice my dodging skills (being in very low armor gives me more incentive to dodge more). After a couple of rounds (I got 12k damage each round :D), I began to think: "Would having a fully heated Cyclops hat and Fencing armor really make a difference at all from the unheated ones I have now?"
So, I have to ask, is there a benefit to heating? I know that weapons gain strength through heating, but I don't think that armor/helms would gain defense...
