Well, since you plan to use silent 120mm fans - which is your best option if cost and silence is your main concern - I would argue in favor of the 2-342.
Since you will not be moving a large amount of air over the radiator fins, any additional surface area provided by the 2-302 will, IMHO, not be worth the added restriction to (water)flow. The area of the face is nearly identical for both models, and the thickness is also the same - so your airflow/ airflow effectiveness should be nearly the same for both radiators. The fact that one will be less restrictive to water flow clearly makes it the best.
