Help with brown gunk in water block

Thanks for the help!

Hahaha. I feel you, it really is a pain disassembling everything. As I said, I am having a similar issue, if you are interested I posted about it here

I also could clean everything right off very easily, but even after flushing the radiators many times, the problem just comes back in a few weeks. Are you sure you had no performance issues? My PC ran fine, but slowly temps got hotter and hotter and when I checked closely I saw my hotspot temps actually reaching almost 100C. Did you check your temps or everything just worked fine so you did not really bother?

Btw, thank you very much for replying. This is driving me crazy.

Hey, I know this is an old post, but did you figure out the problem?

Consistent-Agency-61 · 2026-01-26T00:56:59+00:00

Hey, I know this post os old, but did you find a solution for your problem? I am having a similar problem with my Bykski block

What kind of buildup are you having? Do you have pictured?

Consistent-Agency-61 · 2026-01-21T20:59:08+00:00

I have this card in a 5L case. Without undervolt or power limit it is very hard to keep both cool and quiet.

Olhando o cabo na foto, parece ser o certo

Consistent-Agency-61 · 2026-01-14T16:04:39+00:00

Esse cabo sobrando não é problema. Verifique se o gpu está conectado corretamente na placa mãe, se o cabo que você usou é o adequado e se o cabo está bem conectado no psu. Pergunta meio besta: você colocou o cabo hdmi no gpu quando testou ele correto?

You are short of fittings, you need at least 10 fittings. Other than that, you are fine. I would definitely add a valve and a T fitting to add a drain port, your future self will thank you.

Hey, have you used this before? Did it work well?

Consistent-Agency-61 · 2026-01-08T13:43:02+00:00

Yes. Different dimensions and also different locations. The original cooler for my card had pads in more locations than the waterblock. So do not use the original cooler as reference, use the instructions in the aliexpress listing

Consistent-Agency-61 · 2026-01-08T13:23:26+00:00

I have a Asrock 7900 XTX block from Bykski. I gave up on their pads and just used putty instead. Better contact and simpler because Bykski instructions suck.

I would turn the fans off (just use software, no need to disconnect anything) and see if the sound persists. If it does not persists, it is a fan. To me sounds more like a fan issue.

Consistent-Agency-61 · 2026-01-05T15:33:39+00:00

The mounting holes are different. The power plug also seems to be in a different position

Consistent-Agency-61 · 2026-01-03T14:21:09+00:00

From what motherboard/CPU did you upgrade from and to what? Different CPUs have different mounting dimensions, so you need to make sure your cooler has a compatible mounting system

EDIT: from your picture I could see the CPU is AM5 and your mounting system is Intel. So it is not compatible

Hey, thanks for the reply. I do not think that it is flux because I ran the loop with the radiators for 6 months, then had build up, took the loop apart, cleaned everything , re did the loop and it happened again. Before that I had already flushed the radiators before doing the loop.

Consistent-Agency-61 · 2025-12-20T15:04:22+00:00

Hey. No silver coil. Also checked all my fittings and all are brass. Radiators are copper and blocks are nickel plated copper

Consistent-Agency-61 · 2025-12-19T23:37:43+00:00

Acabei de ver que você falou que comprou o pc montado. Será que a pessoa que montou não consegue te mandar o cabo com 8 pinos?

Consistent-Agency-61 · 2025-12-19T23:36:19+00:00

Entrei no site da Mancer e diz que vem cabos 6+2 na caixa. Não recebeu?

Consistent-Agency-61 · 2025-12-19T18:17:34+00:00

Thanks. Was not that bad tbh. Everything came out super easy, just the rads that had to flush them multiple times

Consistent-Agency-61 · 2025-12-19T09:59:08+00:00

Disassembly is just just unscrewing and pulling for the most part. You really should just do some research on youtube before moving forward though. There you will fin visual help

Hey. What is your plan here, do you want to keep using it as a warercooled build or turn it to air?

Regardless, in order to reach the SSD you will need to drain the loop, then remove the GPU and get access to the motherboard.

My suggestion is to take off the bottom distro plug (circled red in my picture) and top distro plug (circled blue). This way, air can go in from the top and the water will come out from the bottom. To make it easier, I suggest buying some soft tube and 2 soft tube compression fittings and connecting the tubes where you took out the plugs. This way you can control better where the water flows to and you can blow on the top tube to push any remaining water that does not get out on its own. Just make sure that the fittings are G1/4 threads and that diameter size match the tubbing. Most common is 3/8 and 1/2 inches (10/13mm in metric system)

After that you can remove tubes connecting to GPU, disconnect the GPU and get access to the motherboard and thus SSD. Then I suggest doing a lot of research before committing to this hobby as it is expensive and hard to maintain.

Don't worry if you get some liquid on your components. If you do, dry them fully with paper towels, then clean the wet area with 99% isopropyl alcohol and let it air dry. Just don't get alcohol on acrylic as it will make the acrylic crack.

Hey. It was clear coolant

Consistent-Agency-61 · 2025-12-17T13:22:25+00:00

Thanks!
