WATERBLOCKS MIXING

I have already a loop with EK-Supremacy MX. One of my friends sold his 980ti and he gave me his waterblock ( i have 980ti too). Can i add it to my loop with out any problems like galvanic corrosion?
The gpu waterblock is EK-FC980 GTX Ti WF3 . Thanks for your time !!!

as long as the waterblock doesn't contain any aluminium, i see no reason to.

I had a look at the block and it's nickel so thats fine

Ok thanks for your time.My Concern was that the gpu is nickel+acetal and the cpu is copper

Nickel and Copper are very close to each other on the Anodic index.

The closer they are the better, and Nickel and Copper are very close to each other. I've read that 0.1 of difference is about the range that it is acceptable. though I've pulled that number out of my brain from somewhere. Can't remember where I got it from.

Ok nice. Thanks for your time

You always have some mild difference - radiators, if not aluminium, tend to be brass as copper is too soft and some blocks are nickel plated copper, some are just bare copper and others of course are aluminium.

While in a perfect world I suppose you'd have completely matching materials the key in practise is to avoid anything with overly different anodic indexes, such as mixing aluminium and copper in the same loop.

My rads are 2*EK-CoolStream SE 360.
