That is a good point. But without getting too technical (although I'd love too if wanted), there are 2 caveats with your thought: 1. Order does not need heat transfer. Flying birds form a V-shaped pattern (to minimize drag, whatever), fish "order" into a packed school instead of being random, a honeycomb is hexagonal. Those are (near) optional solutions for constraints. There is an analogy with crystal formation but the math is not totally clear. 2. Crystals can have higher entropy than disordered states. Actually, a (crystalline) dense packing of Brownian spheres have higher entropy than a random close packing of spheres.
