Oops, my mistake in the interpretation.
Yes, in that case, the difference is getting down to around a 0.0001C difference based on the tube wall material, since the bulk of the difference I was calculating was due the incorrect assumption of the fin material.
Point still stands though that if the radiators perform better, then it really comes down to the difference in size, rather than what materials are used, oh, and that two fans are being used rather than one over that larger area, so therefore more volumetric air-flow.
