Added EK 6970 blocks and...loop becomes soapy (OK, more like full of bubbles)??

post #1 of 9
Thread Starter 
Was using this config:



With two EK 470s, and I could always see a few small bubbles through the acrylic.

Today, I decoupled the GPU part of the loop with my QDs and slotted two 6950s with the EK 6970 blocks.

I jump-started a second pump, and everything seemed normal...water drained a little, I added it. Then I turned the pump off, sealed the res, tilted the computer back and propped it up against something, an turned the pump on again.

I looked at the acrylic of the 6970 blocks and they are CHOCK FULL of bubbles. I mean like a foam of bubbles.Big bubbles, small bubbles, everything.

Nothing was in my loop except distilled and silver coil. And looking at my res I can see a thin foam at the top and the water is not as clear.

*** happened? I got the QDs to simplify this type of **** and of course this ******* thing happens.

Did you wash the block out before? Used or new blocks? Is it just air bubbles or actually like soap or some liquid in it?

I didn't wash out the blocks. But I didn't have this problem with the other EK blocks. And I didn't notice the foaminess in my reservoir until after I tilted my case (that was like 60 seconds after letting the water run through the blocks).

In fact, the CPU block looks normal. But both the GPU blocks are highly "bubbled up" in pretty much the same pattern, so it can't be a manufacturing defect somewhere in the block, either (unless my luck is completely terrible).

Why would you not wash the blocks? Take the loop apart, clean the blocks, put it all back together, flush several times, then come back.

EDIT: It's probably just air bubbles, not soap.

Sure there's not a air leak or you didn't suck in air?

Air leak? No water is leaking, not sure what an air leak is.

And actually, looking at the water directly (rather than through the acrylic in the res), it is not soapy...but why are there a metric asston of bubbles in the GPU blocks only? The res walls are covered tiny tiny bubbles, as well. And it's not like the pump is making a lot of noise as though it's struggling with bubbles, but again, I see a big bubble in each GPU block, plus endless small ones.

I do hear the res making "tongue-clucking" sounds, though.

This loop sounds to not be bled as well as it perhaps could be, maybe he turbulence in the new blocks has broken up a larger bubble/air void into the foam/bubble situation your in now... the res sucking sound could be air compressing and expanding in the loop causing some surge in the res/pump, how do the pump rpms look?

This sounds like it is not fully bled. Try carefully tilting your case around to dislodge the bubbles. After that the only thing left to do is wait. Bleeding can take hours depending on the design of the blocks, length of tubing, etc.

Thanks guys.

I booted the thing up and temperatures seem within normal range, at least at idle, and shaking the case side from side made the big bubbles smaller inside the GPUs. I'll keep monitoring but it looks like it's not any kind of disaster.
