A vapor chamber over such a small area would have little benefit. They're great at spreading heat around, but when your IHS is already that small it's not much better than solid copper. On something the size of EPYC or Threadripper is may make more sense, but they've done quite a good job of spreading the heat out by arranging the CCDs, to the point where no part of the IHS is likely saturated.

I'd love to be able to test out one of those big-boy chips, but sadly the price tag is equally large.
