[EK] Staining test on nickel plated surfaces - Page 13

Then they blamed the process and switched to EN plating. Now they are back to blaming us again with a test that had a forced outcome. I have an EK EN 7970 block that i bought before I found out about all these QC issues. I fear for my loop now and will be tearing it down sometime soon to see what kind of damage has been done to my block in the short 4 months I have owned it.

There really is no reason to use pt nuke or kill coil. Nuke phn and feser base are the only things i would reccomend adding to a distilled loop. The phnuke/feser base are ph neutral which in the long run is much better for components

likely going with a better looking, actual full cover block that spans the whole graphics card like the Komodo for my next build. Flow rates be damned!

I will also note that within the first two weeks I had to send my defective GTX 480 card back for RMA and during that time I noticed discoloration (less shiny, a dullness) and black pitting, so I took the acrylic top off for cleaning.

Fast forward to last September and a member asked me if my block had flaked, at the time I had no idea what he was referring to, so I simply looked at my block using a mirror and couldn't believe my eyes! It was dirty black then and now it's super shiny copper now as if I had polished the heck out of it! It's most shiny where the acrylic touches the block and is dull copper everywhere else.

I also highly doubt EK has in house plating, these are specialized services. Bottom line. Its likely a ground current carrying issue. I saw the pics, looks like typicall ground current leakage damage to me. I also see that type of damage in cars/trucks and other cloosed loop cooling systems when current is not properly controlled and the cooling system becomes a path for current/volts "however you wish to define it" electricity.

Your didn't understand my point.

I had GTX 580's with Koolance blocks running nothing but killcoil and water and never had any issues. My guess is EK's problems are just quality control issues.

You might want to go play the lotto then.

My EN plated block corroded in about 3 months. I simply saw what I feared would come during a scheduled tear down. After deciding what to do, I got on Sidewinder and bought a matching Swiftech universal block, and am not looking back. EK's stuff looks nice, but I'm more interested in function over form. EK has proven repeatedly that they can't do that, and they can't seem to get their process sorted out.

Hex.

After reading this I'm starting to regret having already purchased 2 of these frown.gif EK-FC680 GTX Full Cover Waterblock - Nickel Acetal
Using 2 of these block alongside a raystrom copper block.
What is recommended to use in distilled water? I won't be adding dyes just the distilled.

Thanks
Dave

A lot of the complaints about the nickel flaking wasn't actually flaking, just staining. Which generally can be cleaned up w/ a bit of polishing compound. This is an EN block I've been using 24/7 since mid February.
