No that doesn't make any sense. If you can fit two 200W systems in the same space as a single big 200W system then using less physical space increases the cooling requirements and the power density might become high enough to warrant exotic cooling solutions like immersion cooling.

Yes, you are right. And manufacturers are packing more and more wattage in the same space over time.

Thanks for mentioning immersion cooling as a potential solution to this; as a shameless plug, we are working very hard to make immersion cooling not exotic anymore at Submer ( https://submer.com ), solving all the problems we saw of the previous state of the art and helping with some of the biggest problems in the data center industry: cooling, power, densities, real estate costs, data center location, DC power distribution, TCO and more.

Exciting times... we are seeing a lot of trends pointing towards our immersion cooling solution and stealth traction from big names.
