I find it funny that people will pay out the nose for 1C (at most) cooler temperatures and will argue about the superiority of such matrerials to the point at which they are splitting hairs. Obviously the auto manufacturers have chosen a proven and reliable design in their heatercores (as in not using plastic tubes and copper fins). They must have done research in this area at some time. And it really doesnt matter that much that the tubes are brass: they have a rediculous amount of surface area and are quite thin. If you look at the half tube on the edge of any heatercore, that is the thickness of the walls of the tube. Nearly any material will be able to conduct well with that thickness. Plus, there is a zig zag flow pattern in nearly all heatercores which (I think) is supposed to create turbulence (and possibly rigidity?). This feature is not found on any computer specific radiator (BIX or those aluminum ones) that I have seen.

I do find it difficult to bleed my heatercore unless the barbs are completely flush with the tank on the inside. If the barbs protrude too far inside the tank, the radiator seems to accumulate air in there, which is occasionally sucked in and I get a little bubble noise in the pump.

Until there is proof that one design is better than another, believe nothing.
