Apparent problem with EK-FC590 GTX-Nickel

post #1 of 11
Thread Starter 
So I just got my first water cooling rig set up; I'm pretty damn proud of it.

Well I let it got for it's overnight leak test, and that was fine, and last night I did a bench mark stress test, and the GPUs stayed at around 40c and the CPU stayed at around 36c. Well this morning I look inside of my block to see the following..

This has been only after one day and it's incredibly disheartening. Is this discoloration normal? It was a very shiny silver color, and now it looks rosey/coppery. Now I literally ONLY put distilled water in this rig, and also took a ton of care to clean and flush all of the parts. No silver, no anti corrosion, not even any PTnuke (though it's on the way). My CPU block is also nickel and the two RADs are XSPC rasa 360s.

Is this block just defective? I have read some issues others have has with the nickel plated blocks. I hope it isn't true! Is this going to ruin/jeopardize the long term cooling potential of my rig?

Edit: Fixed the pictures.

Iv read those blocks will do that after a while, my block looks like that but its quite old. I dont think it should do that over night. Contact EK and go from there, they will ask for pictures then probably ask you to clean it then get back to them before they let you RMA.

most of the time its just a growth on the block and not actually a problem with the block its self, hence why they want you to try cleaning it first.

EDIT why do you have your hose coming out of the bottom of the GPU, why not both on top to shorten up your loop?

To be honest I installed it as per the directions and didn't realize until after I was done that I could do as such smile.gif

What was the time frame? Just a day? I'm doubting it's corrosion unless a massive chunk of aluminum found its way into your loop. If it was only a day, I'm betting it's more gunk from the radiators. What was your process to clean them? Did you clean the 590 block, if so, with what?

It was a days time.

For the radiators I let vinegar sit in them for a while, but not too long. I then rinsed them out vigorously with very hot, almost boiling tap water until I no longer saw any particles in the water. Then I flushed them continuously with distilled water using an old pump I had.

I actually didn't flush the block itself though as it looked incredibly clean and it didn't seem too necessary, but perhaps it was?

Whats the best way to go about cleaning it up? Do I need to flush distilled water through the whole system not as a loop?

Per EK's website, I wouldn't clean unless they tell you to. Fill out an RMA and wait for their response. Be aware that it is pretty late in Slovenia, so you may not get a response until tomorrow, but they are pretty good at timely communications. With this happening after only a day, it's highly unlikely that it is corrosion and they will likely have you open the block and see if the stuff wipes off (it should).

Thanks for all of the feedback guys.

Assuming it is just leftover rad buildup, what is a good way to clean a loop without having to disassemble too much?

I read around a little and found that 10% vinegar to distilled water run through a loop for a couple of hours will do the trick, and then flushed with copious amounts of distilled water to clean out any traces of vinegar. Does that sound like a good bet?
