    No, I will look into other manufacturers.

~2 month update. I had a chance to inspect the new block since the third card was spiking to 95c (could be something wrong with the card) and found the new block from ek is sparkling clean and pretty.

Can't say the same about the other two. These are the one's that I've had no issues with for several months. In comes in the 3rd block, which got replaced in March, and surprise surprise, they are deteriorating the same way and the same spots.

The cpu block is still good but I see a small black spot on the mb block, could be build up from the black deterioration coming from the gpu blocks.

The two old gpu blocks I got back in August, the 3rd gpu block came in in January. The old blocks were in great shape. All this happened as soon as that 3rd block was added to the loop.

Bottom line, when you start accumulating these events its starting to say paint the big picture. EK's quality has gone down the toilet. I'll submit another ticket but I have suspicion it will be turned down.

It is very perplexing that the most recommended and extolled setup is distilled water which is what I using religiously and I have these issues only with the gpu blocks, so far. I have heard a few arguments that distilled still causes corrosion. I would love to see some one test this claim.

I'm thinking of changing my gfx card setup soon, so I'm not sure if EK will part of that path.

Just to recap what I use for liquid:

-1 Gallon of distilled water purchased @ Wal-Mart (purple top, says "distilled")
-Silver strip/coil purchased from Jab-tech.com

That's it. I flush my rads using stilled since its cheap and there is a walmart less than 5 minutes away from my home. The cpu block is not affected and the mb maybe but I have to open that up to find out.

I've got 3 6950 blocks I've had since Jan iirc. I've flushed a few times due to the changing of my loop setup so in that time I've had the blocks apart and inspected. There's no decay in my blocks. I'm on supermarket distilled and ptnuke.

I don't suspect the distilled as the primary culprit. If it was something else, the cpu and mb block would have gone too.

I haven't checked back with EK to see what they found with the 3rd block that went back to them.

Well, I was gonna buy the new 5850 Extreme and an EK block to go with it, but after seeing this thread... yeah, guess I'll look elsewhere. EK is really starting to act like PerformancePC's with their poor customer service and inability to take ownership of their screwups.

The difference between our setups is the use of coils versus ptnuke. It's the reverse of ek's whole do not use ptnuke issue.

For what it is worth I have been running pure distilled only, no pt nuke, no kill coil, for 8 months and my GTX 470 nickel / plexi block looks as good as it did from the beginning. I have no window on my case and all black tube so I don't worry about algae since no light for it to grow.

But now I am nervous and will be checking my block very closely. Sucks wermad.

Do you use an all black, pom/acetal res too?

I'm a little confused on what's happening, your two old blocks are now deteriorating with the addition of the new block? Or the new block is deteriorating already?

Just so everyone is clear- the whole 'do not use PTNuke' issue was related to reservoirs (specifically EK tube res's) and did not IN ANY WAY affect or extend to GPU and CPU blocks. The issue was later determined to be a flaw with EK's process, specifically the use of cast acrylic tubes that were prone to shattering or spidering due to the manufacturing process. PTNuke was shown to have no effect on acrylic whatsoever. It was an unfortunate situation of EK blaming other products before checking their own. The issue was moot for acrylic GPU tops anyway, because the block-tops are machined acrylic and not cast.

As for the nickel-plating issues, and spotting/discoloration, it seems to be evident that EK's nickel-plating process is flawed in some way, or was for several batches of parts. The flaw could be anything from poor surface prep, improper amounts of plating or time in the plating process, it's almost impossible to tell without a more thorough inspection of their process and manufacturing standards. Personally I run EK copper, since the blocks are the best performers on the market, but if/when I decide I want silver blocks, I will definitely not be getting them from EK. Or at least not until their process is proven to be durable again.

I know about the ptnuke bullcrud from ek. The point was more or less making it obvious it's ek's issue with their plating. Since in both cases, wermads and mine, it's not about the additives/coil, it's a crap shoot with ek... box of chocolates.

I agree with you on that, I just wanted to clarify that the PTNuke issue was not related to blocks and plating, some have been misinformed in a number of the threads before and cited it as the reason for the plating; I just didn't want anyone to see that and get confused

It's sad to see EK with such good block designs and such glaring holes in their QC.
