The article mentions different sized radiators but the question I have is the thickness of the radiator. My radiator has a face of 36 sq. inches(6x6) and it is 2 inches deep(excluding fan).
I am assuming that the article is calculating the face as I have, simply by multiplying height x width. There are varying thicknesses in radiators though so I don't know how this is figured in.
Based on this article, there is obviously a minimum size our rads should be, and at a certain point more size gives a diminishing return.
