Mixing Metals in a Custom Liquid Cooling Loop?

[malveymonster]

I am a beginner with PC building and liquid cooling. I am currently looking for parts to build a gaming PC, and I think I have found them, but I am worried about Galvanic Corrosion. The parts I have are Copper, Brass, Silver, and Nickel. These are my questions. 1.Will there be any problem with Corrosion? 2.Should I get an anti corrosive? 3.Would a silver kill coil do anything if I already have silver components in my loop? 4. Does an anti corrosive even work?
The parts I am using are a
Copper/brass core radiator
Silver fittings
Copper CPU waterblock
Nickel GPU waterblock
Silver Valve
Brass T-pipe
I will be using the PT-Nuke biocide, distilled water, and Mayhems Blue Dye.

Thank you in advance to anyone who responds.

Don't use dyes. They can cause problems. Get colored tubes.

If silver touches the water, there's a chance it might corrode something in the future if something conductive gets inside (Ions).

Silver kill coil is an alternative to biocide.

You might wanna add Anti Corrosive or use a ready coolant that has everything needed inside.

Your best option should be ditching everything else and just changing the distilled water frequently if you're worried about corrosion and other stuff growing inside. Every 3 months to be extra cautious. But it's usually changed every 6 months. If you see something weird, change it immediately.

BTW, remember to flush the water inside your radiator and other parts multiple times when you're setting up for the first time. They have all kinds of dirt and other stuff in there that needs to be cleaned thoroughly.

If I get a biocide, anti-corrosion additive to add to the distilled water, will I need to worry about the different metals corroding each other? I also just found that the GPU block is nickel plated copper, not just nickel. Will this make a difference? It is from ekwb.com, I don't know what kind of quality their parts are, bet they seem decent. I was planning on changing the liquid every 6-12 months. would you recommend changing the liquid more often?

Would it be best if I ditched the silver parts and only used copper, brass, and nickel, and then used PT-Nuke in distilled water? That way I wouldn't need an anti-corrosive.

As long as it doesn't lose its potency and rated for them metals, then no.

If you don't scratch and remove the plating, then no.

It's recommended to change it frequently at first to "settle it in", then using longer periods like 3-3-6-6-... months.

For beginners, it's usually recommended to use ready coolant as they have everything mixed inside.

You will still get corrosion even if you use pure copper with vapor distilled water as long as something like dirt or salt gets inside. Water itself is corrosive when it has something conductive mixed inside.

You said it yourself. You're a beginner and this is beginner's anxiety. Just set up your cooler as recommended and change parts if you see something wrong. But I doubt you would need to if you regularly change the water and use the needed additives.

Thank you for all the help, you answered all my questions! I'm really excited to start building my pc, and liquid cooling makes it all the better!

Aluminum. It's aluminum that causes corrosion much of the time.

Silver, gold, copper, brass and nickel are all safe to use in a loop together.

Dyes are typically safer than coolants in terms of having content cause issues and coagulate. Pure water is the most effective coolant, although you will still need some form of antimicrobial agent. Silver kill coils do little to prevent growth.

I haven't drained my loop going on 2.5 years with just distilled water and antimicrobial. Water is still clear.
