Corrosion Issues

post #1 of 24
Thread Starter 
So i finally got tired of hearing that noisy Xspc pump/res so i wanted to use a different one. Anyways, so i obviously had to disassemble my loop. As i was doing so i began to notice dirt (black looking powder/ cloudy black substance) in parts of my tubing. Also once the loop was entire apart i noticed it in my blocks and in fittings as well. So i decided to take my blocks apart and just disassemble Everything. I took some pics (crappy iphone4) of the problem areas that i noticed and the corrosion in which i saw.

Corrosion on one of the many fittings

I am now letting the blocks soak in vinegar to hopefully clean them out, and after they sit for a while im going to throw them in a bag of rice.
Can anyone tell my why i am getting corrosion and how i can completely stop it (if possible) I had Biocide in the loop, no kill coil. I had an rs240 and an ex120 rad as well cooling the loop. Any questions or comments please post!
Any help is greatly appreciated.

Thank You

No kill coil, get one. Best thing to have, even better then biocode, IMO.

Have you ever cleaned the loop before? If so what did you use?

What fluid did you use in your loop?

I've never cleaned it before, but it has only been together since right before christmas.
I'm running distilled water + biocide in the loop. Using primochill tubing too, if that matters, which, i dont think it does.

And you bought the stuff new I assume?

It's usually a good idea to flush all new water-cooling components with distilled water before installing, at least that's what everyone I've talked to told me.

The tubing shouldn't have been an issue, although I have seen some primochill tubing still have plasticizers in it. Not a common occurrence with that brand tubing.

Yes, everything was purchased new. I flushed everything before installing, i've always done that. Yeah, the tubing isnt causing the issue. Im sure it's the metals messing with each other in the block and rads and such. So idk what to do, i mean, im not experiencing bad temps or anything, i was just concerned since i noticed it. Not a big deal, i just want to figure out a way to deter it, if at all possible.
Thanks

Only thing I can think of is replacing the barbs with either compression fittings or a different brand.

Yeah i may have to do that as well. I plan on upgrading everything very soon since i want to do a new build and possibly ditch 1366. We'll see when the time comes, but for now im just gonna leave it and hope nothing breaks or leaks or anything. And if anyone else chimes in and has a solution before i put the loop back together.

Flush everything really good before putting it back together. And like I said get some different fittings. What GPU blcok was that again? I heard the EK blocks had some issues a while back with corrosion.

I am flushing everything extremely well, like i said, it's all soaking in vinegar and then gonna be rinsed, then bag of rice, then back into the computer. It's a Heatkiller block, not Ek. Dont think i'll be buying new fittings yet, maybe later on, or if i actually start having issues. But for now i'll just deal with it.

Be careful with the vinegar, it will work on the corrosion, but you really only need about a 50/50 vinegar/water mix, and don't leave it overnight- the vinegar can eat the copper away surprisingly quickly. I'm not sure where you'd be getting corrosion on these parts- from what I can see you're running all copper. That's a lot of corrosion to be seeing in only two months eek.gif
