The "innovation" is that everything is now attached to a watercooled block.
The rest is marketing: The Cray supercomputer were fluid cooled back in the 1980's, the entire board had an inert liquid flowing across it.

The innovation is being able to run the chips at higher temps without ruining them too quickly.
Haven't AMD CPUs been targeting a 95°C limit for 5+ years already? I'd have guessed servers could do 60°C without degrading a whole lot before switching to more power efficient hardware is available.
95˚C is the core temp, not ambient. My parent comment was probably wrong though, see https://news.ycombinator.com/item?id=48667527
My partner lamented the same thing... Cray was doing this 40+ years ago
Cray used Fluorinert, a chlorofluorocarbon. So not exactly a environmentally friendly solution.
Bad quality of water clogging the pipes integrated onto the PCBs (thus requiring to replace the PCBs) was said to be what were killing those few USSR Elbrus supercomputer installations.
