Copper/Acetal vs. Nickel/Acetal, Merely Aesthetic?

post #1 of 5
Thread Starter 
I'm considering getting an EK GTX 480 waterblock and could possibly get a copper/acetal one for cheap. Aesthetics aside, is there a reason why I should not get copper/acetal, e.g. oxidation?

Thanks!

Copper will oxidize, and while this will not hurt performance in a measurable way, it will turn the copper a green-brown color.

Acetal is plastic.

Considering that you won't be looking at the inside of your GPU block very much, I don't see why you wouldn't want a copper/acetal block.

Also, when waterblocks say "Nickel" they usually mean a copper core plated in nickel.

The nickel prevents the oxidation.

The understanding is nickel + acetal will last a lot longer and won't oxidize. Also, do not mix metals in your loop. Going full copper will be generally cheaper than going with nickel/acetal.

You can mix some metals, such as nickel, copper and brass. Just stay away from adding aluminum to your loop.
