The new direct liquid cooling system allows eight processor boards to fit in a single server node. IIJ implemented Air-Assisted Liquid Cooling technology at its Matsue Data Center. South Korea’s KDDI achieved a 94 percent reduction in cooling electricity consumption during recent liquid cooling tests. Market analysts expect liquid cooling adoption to surge from 14% in 2024 to 33% in 2025. Japan’s engineering expertise and systematic testing approach may provide templates for other countries facing similar cooling challenges.
