This is what posted on XS about this:
Ok, so I have been away all day and I came home to this, yippeee!
Let's look at the facts:
EK nickel plated blocks have an issue, cause is up for debate at this point as I do not see anything other than a report commissioned by EK that states otherwise, nor did the test include another vendor to ensure that it was the additive and not the plating, so let's move away from that for now. I read through this thread, a lot of repeated info and some interesting posts, obviously, there are folks on both sides of this debate and on what should be done. So this is how I see it, like it or not I really do not care.
EK's Statement from page one.
We have also made internal tests of 5 different coolants in an identical hardware setup.
What we found in summary is that:
1. Certain chemical additives based on pure silver and Copper Sulphate that were added to the loops all of these cases have made distilled water electrolytic and with its properties they caused corrosion of nickel plating.
I called it early on. Somehow EK would put this on the user regardless of the simple fact that it is only happening to EK, not Koolance, not Aquacomputer, not Heatkiller, not even Thermaltake is having this issue, just EK and yet it't the additives that the consumer used that caused the problem. Starts with a "B", has 8 letters and ends in a "T".
2. Most of the threads on the forums have stated nickel-plating flaking off, while research have disclosed there was no flaking involved whatsoever.
What do you call when the nickel plating comes off? Naturally occurring? Seriously? Starts with a "B", has 8 letters and ends in a "T".
Effects of these additives were not commonly known. EK is sure that users are using them in good faith. Due to only until recently confirmed effects of these additives to nickel plated blocks, EK have decided to fully replace products with damage nickel plating in order to support customers of EK products.
If it isn't your fault, nor the fault of the plater, why would you go about replacing these blocks at SUCH a high cost to EK? Could it be that in reality this whole report and everything around it is Starts with a "B", has 8 letters and ends in a "T".
You will get a specific EK RMA form from your reseller which can be also downloaded here.
To get the RMA product replacement you will need to follow these steps:
1. Fill in RMA form
2. Make pictures of the block (front, back and corrosion close-up)
3. Send RMA form, scan of original invoice and 3 pictures for each block to email@example.com
4. We will then inform you where to ship the damaged block(s).
5. EK support will inform you from where your replacement block will be shipped to you (in most cases it will be shipped from the location where you bought it)
6. Customer will pay shipping costs for the replacement block and can discuss with the reseller what shipping method to use
7. Customer will get the block replaced and cannot ask for a credit note nor replacement for another product. Only thing that we allow is that customer can chose to replace the product for non-Nickel-Plated block â€“ copper version.
So, I already paid for the block, paid to have said block shipped to me that was sold to me as a quality product and it turns out that it was not the quality product that I was promised. Now I have to pay to have said block shipped back to someone, so that it can be replaced by a new "High Quality" block all the while my system is down or running on air, forget about my time or the other costs. I like Naekuh's idea about using a local plater, it's either that or EK allows for an advance RMA like what Asus does where they ship the product to you first and include the shipping label back to whoever they feel like sending it too.
Therefore until further notice EK Water Blocks Company recommends, not to use distilled water with silver in the loop in combination with nickel-plated blocks, nor additives based on Copper Sulphate.
No other companies have this issue, I mean not a single company, nada, zip. Can we say Starts with a "B", has 8 letters and ends in a "T".
EK recommends only coolants with anticorrosion additive, although our internal test systems of pure distilled water have been found without any problem in 2 months test period. EK Team would like to ask you to kindly spread this information as we would like our users to continue having excellent experiences with EK products.
The replacement form can be filled in until July 31st, and starting with August 1st EK will no longer replace products with such damage as the reason of the damage will be widely known and customers still using these additives will do it under their own risk. The replacement request can also be possible only for the purchases with invoices dated up to June 12th 2011.
It's already been stated you cannot change the terms of the warranty without offering a full refund as said warranty is a contract and both parties have to agree to the changes.
Seriously everyone? I said they would put it on the user and they did. It's friggin twice now that EK has done this and people are for the most part "ok" with this, really? They do not make a product that no one else makes, seriously, you can find an alternative to virtually every single product they make. You can not get a company to change it's ways unless you hit them in the wallet, because that is all they care about. There is no way EK is doing this out of the kindness of their heart, they know it's an issue with their plating and while they fix it, they throw this out there as a smoke and mirror game to keep people distracted. I am sorry, but you are friggin stupid if you buy another EK product while this crap goes on.
