Copper or Nickle

I forget what people said and I can't find it now...

Copper or Nickle water blocks?

The nickel blocks are nickel plated for cosmetic purposes. The thermal conductivity of copper is more than 3 times that of nickel; so there's no performance benefit.
The only real reason I can think of to plate the copper would because nickel oxidizes like aluminum and still looks clean and shiny, whereas copper starts looking dirty and, if you live in an area with high humidity, will start turning green after a while.

EDIT: I wouldn't think there would be a noticeable performance hit with plating either, so it really doesn't matter.

Thanks guys

EK's nickel still has issues, so if that's who you want I would recommend staying with copper.

I still prefer silver plated but I'm the only one doing that (both the plating itself and using the plated blocks) these days.
