Wow, I really don't think a single stage would be enough, I think you'd honestly have to move to cascade (even including the internationally banned Freon gases, I don't think anything less than a 3 HP compressor would cut it, and even then you might hit above 0c). Its really cool board as well, as I love the behemoth VRM, and I have nothing against duel PSU (my main system is TR with 4x Fury, so obviously I run 2x SuperNova 1300s since they are dirt cheap).
Cool concept, but too difficult for normal people to actually run well since they don't have extreme coolers, and (joking, I think this thing would start blowing liquid nitrogen out of the cup if you really cranked it). You really would go through a ton of LN2 per week (I do mean literally over 2000 pounds, probably around 100 hour mark, or 4 days full operation assuming it burns 10L/hour of LN2). That would be absolute madness to try to do... Also extremely expensive. You'd definitely just want triple stage at that point, your cooler after a couple weeks would pay for itself!
I don't care about the electric bill, but my goodness, I don't have access to that much LN2 or no someone that can make a monster cascade for $5k (or even more, I flat out don't know any custom builders). Power is never a big concern for me, but heat density is, that thing would be like cooling a small sun.
Spread it out with 4 GPUs, and that's fine, but on 1 chip? Ludicrous! (hence I love it)
It probably would not be that much worse than 7980XE, for example. The heat transfer is mostly limited going from the die -> internal thermal paste (whether you replace it or not) -> IHS. I guess there is also the option of running direct die, which may help a little. Phase change would work, it would just run slightly hotter. Intel was able to use a Hailea HC-2200BH (2HP) chiller on theirs to get it up to 5 GHz on 28 cores and stable enough that they wouldn't embarrass themselves. The min water temp on the Hailea is 4c unless modified to run continuously. Wonder if Intel delidded their own chip? lol
