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

      You could take cement which has already set and powder it, or just plain lime powder or ceramic/terracotta powder, and mix it with water. I will not set, and likely it will probably have similar advantages.

    All jokes aside, it is surprising to me that this worked at all- I was under the impression that curing cement was an exothermic chemical reaction, as in, produces heat-

    What about a closed custom loop liquid nitrogen system? No idea whether it would evaporate as its a closed loop, but itd be an interesting experiment.

    The solution need to have a lot more water u should also add a bit of soap to the mix as it slows the setting process of concrete

    I was expecting a normal water loop but with a concrete block in place of the radiator. That might actually work.

    I thought you guys were gonna pour concrete over the whole computer. And the concrete would be like a whole passive cooling solution.

    Does that mean you could take ceramic powder that does not harden and put it into your cooling liquid and make it just more effective ??

    Is it possible to get mercury flowing in the cooling system?

  • Alsmamfkm
    Alsmamfkm Month ago

    Err, what did you expect? Concrete curing is a chemical reaction, not drying out. Even with power 24/7 it would happen. You noticed that it flowed way slower near the tubing than in the middle - movement would not help in anything, it would cure inwards until everything is solid.

    Concrete hardens when it sits still. If you turn that off it will be completely harden and your tubes will clog

  • ravioliwheresthespaghetti

    I can imagine that maintenance with this computer sucks ass.
    I was thinking they would use it more has a heatsink like as an air cooler or something like that and not actually using it through liquid cooling.
