Found a research article (article is talking about the research, link is in article though) talking about the problems of thermodynamics in microchips. Basically how it's economically wasteful of natural resources (like water) to cool microchips.
It's a new way of cooling down chips. By making microchannels underneath the die/substrate over the hot areas of say a CPU and allowing water to flow directly over those areas. Initial research has shown 50x greater efficiency which reduces the need for massive water cooling setups in data centers or super computers.
More efficient cooling means less waste of consumer AIOs(you can use smaller ones for same affect) which means less materials used from coolant to nickel, etc. And then obviously for the aforementioned data centers.
