sorry if i didn't make myself clear enough . I would have a thin layer of aluminum right before the water to prevent the battery effect. if for no other reason(think of the highend alphas, alluminum but with the copper heatspreader plate forged in). I have been told that copper absorbs heat quicker than aluminum but aluminum dumps heat quicker. I'm not sure if thats right. I just started studying must of this stuff in college. And i'm just asking much smarter people . (that would be you guys) Also a silver / aluminum heatsink would most likely cost the same as an all copper one but what if it performs better ?
