$GOOG is reportedly in talks with Chinese firm Envicool and other suppliers to secure liquid cooling systems for its AI data centers. As AI workloads grow more intense, traditional air cooling is no longer enough, making advanced cooling tech a critical part of the infrastructure buildout. The move highlights a new bottleneck in the AI race not just chips, but the physical infrastructure needed to run them. With demand surging and supply tight, even major players are expanding their supplier networks globally, showing how essential cooling, power, and hardware ecosystems have become in scaling AI.
