So I am observing some light galvanized corrosion in my loop. Expect what confuses me is that all the blocks are nickel plated copper. Only the Fittings and Radiator are Brass. Neither of which shows any signs of corrosion. So I'm really confused of what causing it though it seems the worse on the block connected the radiator which has the nickel partly stripped and turning green. I took the loop completely apart and cleaned all the blocks, the CPU block had a nasty big green goop all in it. After I cleaned it the block still has all the nickel plating on it unlike the other blocks. Other the replacing the fittings and Radiator I'm not sure what to do.

 

Anyone come across this before?

The only times I'v had oxidation corrosion issues was with EK nickel plated blocks,.. it was years ago, seems the plating was poorly done, and pealed off.

 

Are you 100% sure that there is no aluminum in your loop.  https://www.ekwb.com...nium-vs-copper/

Funny enough the blocks that are showing corrosion is EK blocks. The Watercool Heatkiller is 100% fine. Maybe i'm mixing up pealing with corrosion. But parts are turning green and matches other peoples images. But mine is way less, it only around the seals where the water is flowing less. The rest is just losing its nickle and having a redish look to it.

EK is a no-buy for me because of their shoddy plating and shady practices.

I'm starting to think so also....

Alright so I completed my analysis. After taking apart all the blocks and pump it seems it was a mixed bag. EK 1080 Ti block had machine oil left it in, than the MB EK blocks started to peal and the oil got into the those blocks also.

 

Finally after taking part the Pump I found some white fluid stock below the rotor and than I realized I never took it apart until now. I bought the pump and radiators used and did a quick wash but never fully soaked the rad or took the pump apart.

 

So to conclude I think the left over fluid was interacting with the distilled water and whatever was in the radiator came unstuck after I starting folding and it heated up leaving it in the CPU block since it was most restrictive. Before I was doing work and light gaming and the radiator never got warm, now its like a cup of coffee after a few days. So the EK blocks just suck and I didn't completely flush the used parts. The green i'm seeing is as the nickel starts to peel off. EK will be a no buy for me in the future. I would like to say the Watercool Heatkiller has been in my loop the longest and has all the nickel still.

I have a Heatkiller block that RRTech chrome plated - it looks brand new and I've used it for 5 years now with only a single cleaning.  A few drops of biocide, a silver coil in my res, and things have been happy.  My D5 is going on 15 years old now too...

My entire water cooling setup is approaching 10 years now. I'm afraid of what my Swiftech Apogee GTX looks like after all these years.

Sorry you are having problems with that IR_cow. 

 

Reason I stayed away from nickle systems and run copper blocks only and Automotive coolant. Coated with nothing and never clogs. woohoo.


"It works Because I threatened it. :lol:" - " did you show it the sledgehammer" - "No, A flight of stairs"
"I don't want to be much of a forum Nazi but this situation calls for a hail Bosco and blitzkrieg someone".

If that does not fix it I hop in a Timber Wolf and Blast it to microscopic Particles.
