Is this just staining or corrosion as well?

Hey all, just checked out my "EK-FC 580 GTX+ EN Nickel Plexi" after being flushed in January, and found this:

I have ONLY used mayhem's blue dye + distilled water + Kill coil so no idea what has caused this? Will take a closer look at the weekend hopefully.
 
Looks corroded around the screw.

However, i'd crack the block open and give it a good wipe downs with a damp cloth

If that doesn' work:

Get some purol universal polishing paste for metals and see if that sorts it.
 
It's definitely staining, but there's also a hint of corrosion there as well, between the top of the block and the plexi.
 
Thanks for the replys guys, yer I will drain the loop at the weekend hopefully, open up the block and give it a wipe down and see what happens, I'm sure there's staining but if there's corrision I'm a little worried as I have never seen it on EN blocks.

Not specifically off the top of my head, but there's no reason why it wouldn't.

Hi there,

The two water blocks which you have received on this order are the *EN Nickel Plating* ones which use a different type of electrolisis and they dont suffer from any corrosion issues sir.

Having checked with our water cooling specialist as these are the EN Nickel plated blocks they will not corrode at all and from the pictures it is actually algae and not corrosion on the blocks.

It will be the fluid you have used in the loop which has caused this issue. The only thing I can suggest at present would be to either have a word with EK to see what they say or perhaps get in touch with *competitor!* to see if they can get them re plated for you.

Any reason why they should be able to corrode Jokester?

Also, if not corrosion, then what else could it be if it can't be wiped off with a cloth?
 
The nickel plating is a lot tougher with the EN blocks, but if it's damaged or you use coolant without corrosion inhibition you may suffer pitting corrosion where stagnant water gathers like between the plexi and the top of the block itself.

Why would you want to re-plate a block if it was only algae?

That is a good point, one I didn't think about. shouldn't there be corrosion elsewhere though?

Sorry about the competitor mention, didn't notice it (not expect an OcUK employee to be recommending it :p)

What would be the best way of cleaning then? Just a damp cloth like cleeecooo suggested or anything else I need to consider?
Thanks for the replys :)

Damp cloth is the first step :)

Ats the leaking warranty :)

If you're worried about it, id suggest getting in contact with EK support as this will mean you should get to keep your warranty if they say it's ok to go ahead with cleaning :)
 
I'm not too worried, now I know it's the leaking warranty, I thi k I will just go ahead and open the block at the weekend and give it a good clean etc... Thanks :)

Edit:
One other thing, sorry to bug you :), Can I just remove the screws on the front of the waterblock and the plexi will just lift off I assume and I can clean away?

Just to confirm, see the bit about an inch to the right of the centre screw, is that actually copper coloured?

I thought it just turned black? My corroded 580 block only went black, not really copper coloured.

OP- yep, plexi comes off easily with the screws :)
 
Why is this only happening to ek stuff. We have run dyes in our Ek products both Old and new En version and its never stained like tat before. We even had ek test our dyes and pre mixes with no problems as well.

Thats some realy serious staining there from blue and is defiantly not normal.

Mind you EK are saying not to use a KILL Cooil only with there blocks.

Ill striped down my FC 4060 GTX tomorrow that has blue dye + biocide only tomorrow thats been running a long time and see what its like and get some photos up.

Im going to say some Dye's only stain Porous materials ... And "nickel" that has been plated properly is none porous ....

Its certainly strange that EK nickel plated stuff is currently the only blocks suffering from all these problems. Of course they are probably the largest manufacturer of blocks globally so there is bound to be more SNR relating to their blocks than anyone else.

I remember the trouble with Koolance screws rusting a while back, but nothing really since then.

Aquacomputer don't seem to have so much trouble with their nickel blocks, but they also tend to prefer copper wherever possible.
 
Well i did take mine all out last night and blow me all off them old and new nickel versions from EK are all starting to show signs of ware and tear. my Koolance and other blocks are all perfectly fine :(.
