The design uses a coolant mixture of water and propylene glycol that can operate at temperatures up to 45°C. Critics argue the system does not address water used by power plants and chip manufacturing.What's confirmed:Nvidia claims its new closed-loop cooling design can cut data center water use by up to 100%.The cooling system circulates a liquid coolant composed of three-quarters water and one-quarter propylene glycol.The system can run on coolant at temperatures up to 45
