Copper and Aluminum Galvanic Corrosion

[saaya]

Its been a month since i ran h20 on my blackops here with a koolance watercoolink kit. Thanks a lot to Koolance again!
And many thanks to DIMAS for his benchtable in ferrari red!

CPU Block is gold plated copper, nb block is our 4in1 block with the alu top, so copper and alu mixed, and the Koolance radiator is pure alu. Ive run 1.7v chipset voltage and thanks to the tropical climate the ambient temp is high, around 25 degrees, and its quite humid here, even in the office. I didnt even use destilled demineralized water, i just used plain tab water which contains tiny amounts of minerals, salts and acid, and i mixed in some of the koolance liquid that prevents corrosion and supposedly improved the temperatures slightly as well.

Aaaaaannnnnnd:

*drum roll*




as you can see... no corrosion whatsoever ... the color of the water didnt change, its still clear blue greenish from the koolance additive, and the surfaces still look new. Well, not entirely new and shiny, but they didnt look shiny when i got the board already
Im not sure but i think this board has been under dry ice or ln2 already before i got it, or at least the block on it
The hoses turned slightly milky but thats always the same with the silicon hoses since they suck up some of the water that flows through them.

I will check the waterblock and the water every month or two and will post updates here. For now im 100% sure there wont be any issues whatsoever, even after years, as long as you use an aditive like the koolance one that prevents corrosion. Those additives are very cheap add a nice look to the water, plus they prevent bacteria and algea growth as well, so the question should really be: why NOT use an additive?
