  • 39% (230)
    Yes, continue or consider using their blocks (copper or nickel)
  • 60% (354)
    No, I will look into other manufacturers.

Well, I wasn't sure if was flawed nickel plating until I started cleaning off the green gunk and oxidized copper. Even then, I never really heard of EK having flawed nickel so I thought the copper might have been the residuals of some form of electrolysis happening in the previous owner's loop. As it was only happening in the parts that was touching the plexi, I thought that the copper in the loop might have gotten stuck and deposited itself.

The block was still pretty gunked up so I put it in a diluted bath with one part vinegar and 20 parts distilled water and it didn't really have an effect on the already exposed areas. Not much different from ketchup which has vinegar and even citric acids from the tomatoes. It did happen to create new exposed areas which might of resulted from microscopic fissures in the platting. I probably would of expected the same thing to happen in just plain distilled since that was where the problem first occurred.

I'll check how much it would cost to re-plate them. Either way I'll have to blast them.

for copper cleaning, I use Tarnish, for nickel just distilled water. I'm still waiting for EK's response to my request to exchange the blocks for different ones in copper/plexi. If they don't, I'm going to have them sandblasted and polished. They'll be more appealing to buyers in copper, which btw, the bad ones w/ exposed copper are running a bit cooler than the rma replacement.

oh the irony

boy am I sticking to HK, aquacomputers or koolance for my new blocks in the future

they are known for clogging the pins in water blocks, staining acrylic, tubes etc.

But in fact, i sent an email to EK, they said if you use AT protect coolant or Nanoxia coolant with your nickel blocks....they will honor a replacement if something was to go wrong.

of course the only place ive seen AT protect coolant in stock is the EK Shop how ironic.

You gotten any updates from EK?

I did check my ticket for any response and now the status shows "on hold". Not sure what that means

Hmm, why do manufacturers not put transparent covers on blocks?

Also, what's wrong with reading about corrosion on forums? Plenty of people are quite knowledgeable on forums. Take our machinist friend coolhandluke, or me (an engineer in the marine industry) I'm sure he could explain machining and I can certainly explain corrosion...

They really should, but there should also be acetal versions for those using chilled loops. I know Koolance has windows on practically every gpu block

Yeah, acetal for aesthetic or performance constraints is one thing, but I like acrylic for the simple reason of being able to visually inspect my loop! The acrylic look is cool too, but definitely second to the inspection function.
