aren't the 2 row aluminums better than the 4 core? how thick is the radiator, or more importantly, how wide are the rows? the whole point of aluminum is that you can make wider rows, typically (2) 1" rows. this cools better than a copper/brass radiator with (4) 3/8" rows, even though as a material brass/copper cools better than aluminum. that would make the pecking order:
1. 2 x 1" row aluminum
2. 4 x 3/8" row copper/brass
3. 4 x 3/8" row aluminum
