In the Netherlands we are already transporting “waste energy” in the form of heat to greenhouses to warm them in winter.

Also interesting that the article states that this engineering problem hadn’t been solved before. Google pioneered running chips hotter than before. Moreover, we have had water cooling in consumer setups for ages. (At least 30 years.) So what is new is that all chips have been attached to the loop. I couldn’t find what they did with PSU though.

High end server PSUs also have liquid cooling now. I'm not quite sure of what temp ranges they run in though.

Apparently SuperMicro also has an existing solution. They are stating very similar numbers: https://www.supermicro.com/en/solutions/liquid-cooling

I think Nvidia are being a little disingenuous here. If I understand correctly, Bull/Eviden has already solved this problem and is in production in JUPITER.

If I am not mistaken, Bull's warm water cooling requires water at ~30°C, so 45°C is still an improvement.
