Just bought this pc and was cleaning it out when I noticed all this growth within the water cooling lines and reservoir. Is there any hope in getting it cleaned out or do I have to replace them?

    Buying a custom loop rig just calls for trouble, but im sure you cant take it back now…

  2. Drain it and soak the loop with white vinegar

    Looks like an opaque fluid that might have separated. Really difficult to see with the pictures.

    At anyrate, you should flush the loop anyway(with distilled water). Then go from there.

  4. I’m an idiot and someone will probably tell me this is a bad idea… but Iodine should kill whatever it is.

    Doesn’t look like growth looks like one of those fluids that that had shimmering junk in it, dealt with that stuff in the past fortunately is cleanable unfortunately your going to have to do a lot of loop flushing to get it all cleaned up.
    Last time I dealt with it I initially did hot tap water with vinegar at roughly 70/30 split ran about 4l of that overall through the loop usually fill let run for 30 mins dump and fill again I just kept going with that until I wasn’t getting any more debris then I did a proper distill flush.

    Saying all that I still had some of it trapped in the blocks by the end so a proper teardown and clean would be the most recommended but depending if you want to go that far is up to you there definitely wasn’t enough of it built up in my case to worry but can’t guarantee the same for that loop.

    Buying someone else custom looped rig without knowing how to work on them is crazy…

    I don’t know much about PC cooling loops, but I would disassemble, and run a brush through everything, the put it back together, and refill with fresh coolant.

    As others said, clean it. You could run some rubbing alcohol through it too maybe do that after some distilled water

    You can always clean it. You’re gonna have to drain the loop and disassemble the entire PC and clean each part one at a time but it’s possible. Also consider adding a bio-cide to your loop to help prevent growth. Also change the water every 6 months or so to keep it clean. A good loop flush is always a good thing.

    Also I saw some users suggesting rubbing alcohol to clean the loop but please do not do this as it can ruin rubber seals and cause leaks.

    You can get it clean but you have to take everything apart. Tubes, pump, reservoir, water blocks.. everything.

    Brand new rads will suggest you give them a diluted vinegar soak and distilled water flush to get out the sediment. If you want to be super thorough you’d do that here and redo the pipes as well since that fluid looks like it’s been in there for awhile.

    The quick solution and probably the best is to go an buy some gallon jugs of distilled water and just flush the system a few times so when you do it’s mostly just the water emptying (probably never get it perfectly clear with this much settling and build up) and then run it through with new fluid
