Water Cooling Metal mixing

Hi,

I have a fairly large loop and wanted to ensure that all metals that have been used should not cause me any concern.

What made me think about this more in depth was a small printed sheet of paper that I recently got with an EK water block. Which is...

EK FC7970 DCII Full Cover Waterblock for ASUS design Radeon HD 7970 DirectCU II Graphics Card : EN Nickel Acetal

- Base Material Nickel

- Top Material Acetal

Here is what the paper said:



I also read on the Koolance web site this....

Koolance's product warranty does not cover the use of 3rd-party coolants, coolant additives, or corrosion. Koolance LIQ-702 or LIQ-705 coolants are strongly recommended to help avoid issues with mixed metals or biological growth. Additionally, do not use aluminum with bare (unplated) copper or bare (unplated) brass in the same system. Do not use silver with nickel in the same system.

The Silver with Nickel I was also concerned about.

Here is what I have...

- The materials used on this reservoir are a classic mix of Acetal, aluminium and acrylic.

OTHER METALS:

Silver Kill Coil (in res)

Should I remove the Silver Kill Coil? To prevent issues with Nikel?

The silver coil has a discolouration to it which as far as I know is normal as this is the protection build up (?)

Is there any potential threat to what I have in my loop corrosion wise?

Any advice great fully appreciated.

why not just use a premix like mayhems? save yourself the trouble

hm, well that's a work around and more of a way out of knowing if there are any underlining issues.

I'd sooner know.

most of what is said above i am unsure how people think they will react.

Your silver coil will be fine with the copper... as both are solid.

the copper (II) sulphate will not react with the silver.

distilled water won't cause corrosion with nickel... it's not like iron that corrodes very well with water and air.

I thought it was the Nikel plating and silver that they say is the issue?

Here is something that makes me wonder...

If you move to 2:30 in this video..
Is this not a new res from EK?

I have been using the XSPC Rasa 360 kit with a nickle GPU block and a silver kill coil for 2 years. I have not seen anything that concerns me with the cooling loop. I know this is not very scientific but I have no issues with these components.
