I just completed a new custom water loop and was careful to flush out all components.  However, I just noticed some sort of grey blob in the block.  I turned the pump up to 100% and much of it disappeared, but some of it remains as shown in the attached image.  If I drain the loop, is it possible to get into the block and clean via one of the ports?

    No idea what it is --> Or where it came from
     
    Did you flush the pump, fittings, hose & the Hydro Copper also ?

    Kind of looks like a piece of drilled or shaved plexi from when the block was being machined but hard to really tell.

    Either a small piece of soft tubing or part of something.   Carefully take the block apart but make sure the seals are put back into place and leak test it (12-24hrs) before firing it all up again.

    I'd try to flush the GPU water block ---> before opening the block
     
    Use hoses to keep the GPU dry while flushing - if any doubt let it dry before putting back into PC
     
    Remember these blocks are only designed for Low pressure.  Best to use the pump (nice if you have a spare) --> your house's water pressure is too high and can damage the card seal

    Is it possible to slide something into one of the ports to get to that spot and wipe it clean?

    It would be very difficult.

    may have to flush it or leave it.  Personally,   I'd leave it if it meant taking the block off the card.   hopefully, it will end up in the reservoir.

    I respectfully disagree.  If that is plastic, it well eventually melt into your fins.  Not to mention, that might pass to the CPU block if that somehow gets through the GPU block.  Happened to me once when somehow a small piece of tubing got into my loop and melted onto my CPU block.
     

     
    I say take apart the block (at your own risk) is the only way to clear that thing up but again, make sure the seals are back into place and leak test for hours.  First make sure if it keeps your warranty intact and go from there.

    It will not melt into the fins.  The fins don't get hot.  I do agree that blockage is a concern.

    Check my image above.  It was a small piece tubing.

    If you drain the loop, you may be able to remove the outward facing port and use an old wire plastic coated clothes hanger with a piece of microfiber cloth to clean the “blob” out.

    The risk you run is the wire not fitting through the port properly, the cloth falling off, or even scratching the block making it look worse. EVGA does not use an intricate pass through design like most other companies. Their flow channel goes directly in through the port, over the vram, through the pass through over the core, over MORE VRAM AND SOME VRM, then directly out of the other port, so it is definitely 100% possible.

    You may have better luck gently taking the block apart and cleaning the plexus part with a microfiber cloth. It is much less risky, and won’t take all that long. The longest part will be verifying that the o-ring is properly placed so that it doesn’t get pinched or cracked when reinstalling the block.

    If the water flow is completely obstructed, sure, it could melt.  But, normally, no, it is impossible to melt.

    Highly doubt it would melt.  It's constantly being cooled by water.

    Believe what you want, I know what I saw.

    I believe the copper plate is always warmer than the cooler liquid passing through.
     
     
    EDIT:  Here's a closer look.  I should have taken a pic before I took apart the unmelted part of the tubing that was connected to the melted part on the fins.  You could see the colors from my bloodshed red soft Primochill tubing.

    If your CPU core is 75 degrees celsius, how hot is the fins/micro channels? Less than 75 degrees celsius. Let's say 60 degrees celsius (15 degrees delta T between Tjunction and die, paste/solder, IHS, thermal paste/liquid metal, block, cooling fins/micro channels). Very generous for you. What temperature does acrylic melt at? 160 degrees celsius. What temperature does PETG tubing melt at? 235 degrees celsius. What temperature does PVC melt at? (the most cheap and crappy of tubing) 100 to 260 degrees celsius depending on additives.

    None will melt at 60 celsius.

    You must have been using the cheapest of tubing, had complete blockage in that section of the block with all water evaporated/air pocket, and the CPU must have been running 105 celsius for many minutes.

    I would say that it is way more likely to not melt than to melt.

    Soo... back on topic? Maybe a new topic to talk about plastic, rubber, and PETG melting points?

    OP already stated that some of the Blob broke free and has moved somewhere else in the loop after turning the pump up, so therefore it isn’t a solid piece of plastic or tubing. The blob moved somewhere in the loop, because it definitely isn’t something placed by David Blain or Chris Angel.

    the topic is the thing in the clear acrylic.  That you can see.  surrounded by liquid.  That cools the thing.  That you can see.  That even if it did get in the fins,  small enough not to melt.     If you wanted to get at it, maybe open one of those ports and used a curved paperclip or something to retrieve it.

    It’s definitely not a solid piece of tubing. When the pump is running full speed, you can see it slowly breaking apart, even sort of dissolving. I had already planned on switching from a clear coolant to a colored one, so I will be draining the loop anyway. I’m hoping I’ll be able to flush it out. I was even going to vertically mount the GPU, but there seems to be an issue with current PCIe riser cables and z390 motherboards (unless someone can clarify otherwise).
