Is this rust?

I disassembled my old 980Ti's and found this. One is worse than the other, but the other is also having the same problem.

Weird, what caused this? I'm using only EKWB stuff (even the coolant is EKWB premix).
Do you think even the CPU block and radiators are affected?

Algae can be brown.

I would take it apart, scrub with vinegar and a tooth brush and see if it helps. Remember not to use alcohol as it messes up the plexiglass.

Unfortunately these blocks are known for corrosion. EKWB doesn't do the bang up job they once did. At the same time, sometimes you need to clean better, flush more or add a silver coil.

Best of luck!
 
How old are the blocks? It looks like that same thing EK had a while back with the nickle plating getting all kinds of fuxxored.
 
It looks like the nickel plating is wearing off and the underlying copper is being exposed. Do you have a silver kill coil in the loop by any chance? You don't want to scrub that as it will only pronounce the effect.

I tried using soap water as it was nickel copper and I can't use vinegear. It didn't help much.

Nope, didn't add anything else except EKWB's own coolant, which should have everything needed.
 
I'd get in touch with EK if theyre only a year old, they had a problem with their nickle plating around 2012-2013, if you google "EK nickle plate flaking" youll see some similar pics to your issue, but it was supposed to be fixes around 2014

Why can't you use vinegar?
