    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.

      Why not run water to a block concrete with water tubes to dissipate the heat into the block of concrete as your heat sink

                  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.
