    Lots of whacky computer water cooling projects have been attempted before, but none as crazy as concrete - and it turns out it works amazingly.

      Linus, try adding a concrete plasticiser. It will make it a few times more runny with same amount of water.
      Chemistry behind plasticizers is mind blowing.

    Is there a way to add like mineral oil to the concrete or something would work against solidification that can work stable. And I would think this can work but only something that will stress the pc like server based.And I think concrete is something like a double-edged sword here especially for using it for high heat exchanges...like the spikes. It might help dry it out quicker and solidify. Could a crusher type of filter in a special modified chamber be made which could even be 2food processor blades continuously turning making smaller particles be possible. Also concrete is made to turn solid. Win for concrete on both sides really.

    If I saw this a few months ago, I feel like I would've fallen for it
    Although now I kinda wanna see it for real
    ....... so what actually went in the system? Or was it just a dummy water cooler? Or were the sides painted grey?

    ok, i know this is an april fools thing, and I am SUPER late to the party... but seriously. DO NOT DO THIS. it may work for a little while, but concrete is literally built to be something that hardens. AND Quiccrete (sry 4 spelling) is made to harden even QUICKER. I mean, come on!! If you want to destroy a few good systems for a liquid ceramic that sets anywhere from 40 minutes, to 10 minutes, and it totally not worth the practicality of it, then fine. But at least someone put the warning out there.

    if you add sugar cement can't set up so this could be a real thing especially if you made it more watery

  • oShadowkun
    oShadowkun Month ago

    Haha wow, you can really tell they've never seen quikrete before, And why'd they use a mixer?? I used to mix concrete in a bobcat bucket with a shovel, they could've just put that amount into a cup hahaha.

    Thermal paste cooled pc

  • One of Billions
    One of Billions Month ago

    Any DIY er knows concert/cement hardens through chemical reaction not air exposure. Take a blob of wet concrete and drop it underwater or in a closed circuit and it will harden like a rock just as if exposed to air. It also gets very hot in the hardening process. So wtf, were you for real?

  • Beau Moloney

    you will just never be able to turn it off haha

  • voiox

    Initially I thought they would just fill the case with concrete and let it harden and then use it as the heaviest PC cooling block ever(!).

    Wow, for the amount of concrete you made it really would have been less effort just use a trowel or shovel, then someone wouldn't need to clean the mixer...

    A little suggestion for a better version of this:
    If you add salt to the mixture (actually not much is needed) the concrete never hardens out. That would obviously solve the problem when turning off the system.
