Just a quick note to add to this thread, as it's only just been pointed out to me by Bill elsewhere... the Koolance radiator core HAS been tested via what we would consider to be "the normal approach"... http://swiftnets.com/Technical/Asses...erformance.pdf

The Corsair Hydrocool radiator is the same core, same characteristics, same manufacturer... just upscale the frontal surface area to match the comparison rad and extrapolate. ie: In the Swiftech Article, a 120.1 footprint rad is compared against everyone else's 120.1 footprint rads. The results / running order would be the same if upscaled to 120.2 vs 120.2, and ditto 120.3 vs 120.3... Someone with the maths knowhow could extrapolate this to match the surface area of the specific Koolance radiator, then overlay that against the rest.
