Poll Results: In light of EK's nickel failure, will you buy their blocks?

 
  • 39% (231)
    Yes, continue or consider using their blocks (copper or nickel)
  • 60% (354)
    No, I will look into other manufacturers.

They usually added a piece of stainless to accent the looks of the block but recently, they have been using stainless steel tops. I guess its working for them since their continuing with this design.

I'm thinking that a fine amount of silicon caulk spread over that center portion could in theory stop corrosion in its tracks. Basically like spreading TIM on a CPU. Anyone ever tried that setting something like that up prior to running a new block? If it's okay for automotive thermostats it should be okay for a GPU block I should think. with water being blocked out of the gap it should withstand the minor pressure that our water cooled systems could generate. thinking.gif

Obviously the thing to watch out for would be squeezing it into the flow chamber when the top is tightened to the block. mellowsmiley.gif

It's all the way down to the copper now. I think it is strange that this is only happening in the middle section. It doesn't seem like flaking is the issue here. I think a form of crevice corrosion is happening, but I'm only familiar with the stainless steal type in a marine environment.

thats the exact area where my block appears to be corroding from :/

That is thinking in the right direction thumb.gif. In the boat industry, if you have exposed metal in the water you are highly advised to cover it as the most simplest approach. Usually a nice epoxy coating and then paint works pretty well. For our blocks, one could could even use clear nail polish, as some of use do to coat our mobos for LN2/DICE benching to keep water off.

i recently purchased the EK 680 Nickel + acetal before i read this .....

so.... is the new ek 680 gtx nickel + acetal fixed ??

and my other question .... is it safe to use this nickel wb in my wc which is using a tfc 360 xchanger radiator ( i think it's copper fins and brass end tanks ) and swiftech apogee xt (copper) wb ?


if both or one of my questions is No, then should i change my gpu wb to the EK copper + acetal wb ?? because it's the only option i have since thats all the shop may have as an alternative.

I have yet to hear a claim that the nickel degridation has affected someone's loop and performance. In terms of performance, I can personally attest that you get a slight (very minute to tbh) increase in thermal performance.

It all comes down to the looks, resale, and quality that one is expects when considering an EK nickel block. Check your blocks on a periodical basis and if you have any issues, inspect or open your block (no worries about breaking warranty, supports recommends to open your block, especially acetal top ones) and look for any degradation.

I should think that the only hit on performane is if the nickel breaks free of the copper and floats around in the loop. Could cause blockages and blockage is a performance nightmare. Might also damage the pump. But if it's not a flaking kind of corrosion it should pose no immediate effect on performance. smile.gif

Now remember I freely admit that I am certainly no expert. I'm just using a bit of applied logic in this regard. Typical disclaimer applies here. wink.gif

My EK FC-480 block has been peeling it's nickel plating for two years now and my temps are exactly the same as when I first installed the block, the nickel that comes off is so thin (.004) it's almost immeasurable. The only thing that makes this nickel plating a bad thing is looks, not performance. I have never heard of anyone having blockage in their loops because of nickel plating jobs gone bad, my water looks crystal clear just like the day I filled up the loop. If you are still unsure and you want quality there's always Koolance blocks.

EK switched to the newer "EN" plating process around July 2011 if I recall correctly, and everything manufactured since then is EN. The only chance to get a block made under the old plating process is if you bought a block that was available at or before that time, either second-hand or possibly from a vendor trying to clear out the last crumbs of that old inventory. Since the 680 only got released a few weeks ago, it's safe to say it is the EN version.

EK still hasn't replied......I'm inclined to believe that they're ignoring me now maybe....
going to leave another reply on my ticket that I opened. Sent them the email last night and before this incident they always reply quite quickly.
