To my knowledge water used in water cooling is de-ionized water/coolant. It being de-ionized coolant there should be no risk, it if was standard water (aka ionized water) you'd potentially have issues

And it's likely it's only nickel plated, underneath is still copper. Nickel plating just helps prevent copper from corroding/changing colour.

Don't think I've seen any pure nickel blocks. Silver yes, but not nickel.

Aluminum and copper is something you do not want to mix. Copper and nickel is fine.

Google: Galvanic Corrosion
Galvanic and Corrosion Compatibility Dissimilar Metal Corrosion - Engineers Edge


As you can see Aluminum is -1.66v at standard reduction potential, that means it's VERY easily reduced. When mixing with copper in an aqueous (and ionic) solution, aluminum ions will precipitate into metal (reduction), and solid copper will become copper ions (oxidation).
Overall voltage of the Cu/Al cell will be +0.34 - (-1.66) = around +2.00v (which means it's spontaneous)

If you mix Cu with Ni the resulting voltage will be +0.34 -(-0.25) = around +0.59v (spontaneous but it's not very strong since Cu and Ni are very similar)

Like i said, water cooling coolan is de-ionized solution so it shouldnt be an issue. Thanks for bringing out the science (i was too lazy too)
