Orange and White residue? Rust and Calcium build up?

post #1 of 21
Thread Starter 
What could've caused this? That was an ek nb/sb block for evga classified board and the two compression fittings connected to it. I did put a silver coil on the tube that is connected to one of those fittings. Anybody here have had the same experience as I have? Forgot to tell you guys that I was using distilled water only and no additives except for 3 silver coils. The cpu waterblock is ok as well as the two radiators and the reservoir.

what brand fittings are those? the white/grey looks like Galvanic corrosion to me, and the orange might be as well, although it does look like rust.

I does kinda look like the rust that you would get if you had water flowing through it, because the water would "smooth" it out. Maybe there was some sort of foreign metal, which could cause the localized corrosion or build up of stuff.

Can you remove it by wiping it with a que-tip or something?

The 'rust' colored residue, yes I can wipe it off, but the white seems to be permanent. I can't even scrape them off with my fingernails. The fittings I use are all Bitspower. Do you think the silver coil might've contributed to it? Or I probably got a bad batch of compression fittings?

open up the block and check the inside of that. I really think there is something foriegn in your loop causing that...

what was your loop order?

what are the other components of the loop?

Taken from the Galvanic Corrosion wiki page,

Quote:
The common technique of cleaning silver by immersion of the silver and a piece of aluminium in a salt water bath (usually sodium bicarbonate) is an example of galvanic corrosion.
Any chance that there might of been a little salt OR a slight electrical charge coming from the motherboard on the plates?

Further reading in the wiki gives us that
Quote:
A rather more spectacular example occurred in the Statue of Liberty when regular maintenance in the 1980s showed that galvanic corrosion had taken place between the outer copper skin and the wrought iron support structure.
This points to maybe some iron is in your loop, which could also be what is causing the rust. Don't know the metals used in a pump, but generally motors use iron, check for leaks in the pump as well.



Edit>> Here's the link to the wiki.

Swiftech cpu block and pump, xspc radiators, ek nb/sb wb, Koolance reservoir, and red tubing. I'm gonna try opening the ek wb since that is the only one where the residue is present.

I have no idea if it had iron or electrical charge in it. I did turned off my computer for a week when I went to another state though. I bought another ek wb to replace the slightly rusted one I got(don't want to reuse it). Any compression fitting that you guys can recommend me besides the Bitspower one?
