What are you using for your loop, specifically?

Blocks, Rads, Coolant?


I'd be inclined to think either/or/all of these potential causes:
1. Mixed metals reacting.
2. Coolant not fit for the metals used
3. No biocide used - algae buildup
4. Incorrect biocide used - reacting with metals or coolant.

What kind of water are you using? What treatment? Your fittings also look like you are mixing metals.

I'm using one Radiator with 2 fans, and 2 block for my 2 gpu and pump.
I didn't use biocide

Only distilled water, and I don't have any anti corrosion or algae growth inhibitors in the loop.
and idon't know anything about mixing metals.

Between (very likely) mixing metals & a lack of anything preventative regarding algae etc, this was always going to happen, unfortunately.

No disrespect intended, but if you're running a custom loop, you should be able to state the metals used (or at least the specific components) near off by heart.

Definitely a lot of research required before diving into a custom loop.

Whether or not too much of your loop is salvagable at this point, will depend on the extent of damage.

Where'd you get the fittings? Those don't look like proper fittings for a water loop. They look like male air fittings you use on air tools.

Dude those are air tool fittings, you have some made from zinc or steel, and some made from brass.

When brass and zinc or non stainless steel are in galvanic contact the zinc and iron corrodes, that's what is causing the brown water.

None of that stuff is fastened properly either, it's just a matter of time until a hose blows clean off and sends your entire computer to the junk yard.

Turn it off, drain it, and let a pro set it up properly

Yeah, that's a complete nightmare from start to finish. A disaster in process. Only thing left is the fantastic finish. Some things cannot be solved using trailer park solutions.
