[metarinka]

sounds like a nice guy at least, computer rads work much differently then car, just in the fact that most are low volume, low pressure with only a marignal difference over ambient. Where as cars the coolant is right around its boiling point and uses forced air. At any rate does aluminum become more effecient at elevated temperatures and at bigger temperature deltas? I know steels thermal resistance and specific heat change at different temperatures.
Also if the radiators were different that alone could warrant some improved performance or what not. I doubt its the case but does aluminum have a lower coefficient of friction with water? are the fins and such built or joined any different? as there's a big difference between mechanical bonds and metalurgical ones when it comes to heat transfer also; spacing, wall thickness, surface finish etc can effect performance
juss wondering if anyone has the lowdown on radiator construction.
