EK - 8 days and possible corrosion - Page 5

post #41 of 77
Whoa guy, EN Plating is known to discolor, but it also bonds stronger and more uniform. Most WB Companies don't do EN plating, EK sought it out as a compromise between their old (apparently recently inferior) methods of plating which were causing corrosion issues due to a non uniform coat (This is likely a surface prep issue, not a nickel process issue) which provide a brilliant shine with medium corrosion resistance and a moderate variation in uniformity to a more uniform, less brilliant shine with much more corrosion prevention, and almost perfect uniformity over the entire surface.

BOTH methods can easily fail if surface prep isn't done properly.
I'm not defending EK, but rather clarifying that their response on EN plating is justified without seeing pictures - EN Plating WILL eventually dull, though it can usually be polished back up with just a lint free rag and your breath.

So much this. Waterblocks are *NOT* coated in lacquer, the polished shine comes from the machining process and plating. Plating =\\= lacquer. A lacquer coat is only necessary on untreated copper surfaces because copper oxidizes like mad. This is also the reason I will not purchase Danger Den blocks - Solid copper + no laquer = brown/green block within a year or so. Now that they started plating their stuff, I may consider.

Hmm, so what was the brown crud in your first pic?

Ed, your brand is taking a beating. I personally believe your getting the Fox News treatment and this is being blown up like you just bought a million dollar bus. You need some deft PR handling right about now, and the type of posts you make should be less standoffish. Just my two cents.

I am with you. There was definitely an issue with EKs plating process in the past, how wide spread is unknown, but it was enough of a problem to change the plating process for EK. Now we have this new (for EK anyway) plating process, who knows how well it was implemented. Maybe there is a problem, maybe not. But its way too soon to condemn EK and say they are going to be shuttering their doors. I have been using a simple stratey with EK, don't buy nickle plated products, stick with the copper. Has worked so far. I did buy one nickle plated product, no signs of deterioration..... yet....

There is oxygen suspended in water. Distillation doesn't remove oxygen. The levels of oxygen get lower but that's only because the higher the temperature of the water, the less oxygen it can hold.

Distillation can only remove solids or other liquids that have a boiling point higher than what's being distilled. Oxygen is already a gas i.e. past its boiling point.

Guess EK will not be an option for me in the future for waterblocks....don't want to deal with this type of mess =(

See if you can RMA or return that block and get a XSPC Raystorm.

I trust XSPC over EK, especially nowadays.

have had my rig running for 6+ months and my water is still crystal clear. EK must suck bad as my kit is a $100 XSPC...

If you were to use a corrosion inhibitor (or premix coolant), the copper stays copper colored - even after a few years. Everyone seems so set on using "pure" water though.

EDIT:
I see what you are saying.

However, you need a significant amount of time and oxygen to oxidize copper. 8 days really shouldn't do it unless there is another catalyst at work. Perhaps the heat off the CPU? But even then, there shouldn't be enough heat.

plenty of reasons

since its based near the sea/ocean; ocean spray containing salts and minerals and since its also based outdors; rain and enviromental elements

a WC loops is enclosed dude....not exposed to environmental elements

Has nothing to do with teh ocean.

Copper roofs do the same thing.
