I’m not sure I’m following the end game here with freezing it. From what I recall ice is actually a pretty decent thermal insulator and since a given mass of ice is larger in volume than the same mass of water, you’d end up with a hole melting inside with… weird things happening as far as pressures go. If the goal is to keep the processor nicely chilled, you’d probably be better off running liquid water over/through the block of ice and then keeping the coated board chilled in the ice water bath. If you’re trying to get below 0C, you should probably keep using a liquid with a lower freezing point instead of having the board frozen in a block.

> I’m not sure I’m following the end game here with freezing it. My kids playing on the Mega VR headset and complaining about it getting hot is one example of my line of thought. Let’s say you have to absorb the heat generated by a given amount of electricity but want to do it in the most weight efficient way possible. It turns out that regular old water has basically the highest latent heat of fusion at room temperature and pressure, which means a block of ice can absorb more heat by melting than pretty much anything else gram for gram. What if the VR headset could just freeze itself overnight and then no fans or reliance on dissipating heat into the external environment but instead into the ice. It’s probably stupid but I do know water is the best know molecule in terms of latent heat of fusion per gram at room temperature and pressure.
