I agree the ek do have issues with some of their blocks but i also think that people are dreaming if they think a plain distilled loop with a kill coil and no corrosion protection is safe aswell esp when mixing metals / plating etc.
not here to repeat myself but at only 6 months mate, my block was stuffed. 6 months is no way near long enough to create the issue to the extremes mine was at. it was there plating, plain and simple. if its metal mixture than why have none of my aquacomputer blocks done it in the same period of time? still run the same water, same LU, same silver, same fittings, same rad, same pump and so on.

but its not just that, its the way ek went about it all and blamed the customers for 3 months as its our fault with what water we use and so on. i called bullshit. within good time though they pulled there heads out of there ass and claimed the warranty process. but it was to late. everyone was already over there bullshit and had enough. me included.

it was more about how they went about it more than anything else for me. they were assholes. simple. remember all there expert scientific testing and shit they did to prove everyone wrong? but yet they ended up going ok we will fix them all now. good luck to them, hope there business fails.

its no way to treat your customers especially when your one of the largest watercooling company's in the world.

whatever lol im just pointing out that i have a had ek blocks aswell with proper automotive corrosion inhibitor in the correct mix and never had an issue. Running a plain water loop is just asking for trouble. Just because it doesn't happen with some other brands doesn't mean the block is necessarily faulty it just means they react differently.

Like i said i know some of their blocks have issues but it doesnt help when nubs mix 3 different metals in a loop and run plain distilled water and expect it to last LOL. There is a reason why all commercial cooling systems run inhibitors.

ummm hard to tell from the pic but i would say that is polished copper and nothing more than oxidization of the surface area / finger prints etc...

Nope.

This is a 370

This is the build log

And this is the block.

looks fine to me? its just some oxidization on the surface area. Heat mixed with high water turbulence through the channels and high pressure would be more than enough to do it.

People need to stop worrying about making their loops pretty and clean and run the right stuff for the job, plain water is not good for longevity. Im running a 3-4 metal loop and there is no staining of blocks / corrosion etc, tubes arn't great but they never last.

In the end a bit of discoloring isn't going to hurt unless stuff floating through the loop clogging the channels and restricting flow.

The part where the item description says Nickel-Plating should clue you in to the fact that it isn't polished copper, and Nickel doesn't oxidize to orange...

Any word on Koolance replacing the block under warranty? they recently replaced the front of my RP-452X2, sent it from the USA at their own expense. took about 4 weeks as they didn't have any stock.

So sick of this EK bashing going on. From what I understand, EK didnt blame anyone but merely stated the corrosion COULD have been caused by a number of things. And this was during the third party testing. Then once EK realised it was most likely due to a plating issue, the offered replacements no questions asked.

I dont see the problem? Just a whole bunch of impatient retards who wanted replacements right there and then.

Reading the thread, they initially were not going to replace it as you werent using their coolants, apparently the member had great difficulty in getting it replaced and had to climb the management ladder to have it done. He was running distilled + silver.

It is a bit odd for a nickel plated copper item to flake and not show any copper beneath. All the flaking issues that I have seen images of seem to have copper beneath, rather then what seems to be more nickel.

does seem a bit odd
may have been double plated?
it appears to be this one
http://www.ekwaterblocks.com/shop/bl...al-nickel.html

i tried to reuse my original ek gpu blocks this week
they only had minor flaking to begin with.
soon as i started the pump,
the res turned into a silver snow globe

AC FTW

Bit unfair. I was going to rehash everything but it's been said before.

Could be argued that the AC plating is not the best

Or maybe nickel plating is generally not the best idea - so far on this forum we have a AC tube res with plating coming off from sticky tape, - EK, a koolance-370 loosing its plating and not being replaced.

Full cu FTW

some of u new guys seem to think its just about the nickel failures
and completely forget about or are unaware about all the other issues ek has had in the last 2 years.
failing o rings
cracking resz
un-machined blocks
etc...
and the way they were handled at the time.

google is your friend
