    Physical AI Infrastructure Expands Demand for Connectivity and Data Center Cooling

    Question

    Physical AI Infrastructure Expands Demand for Connectivity and Data Center Cooling

    Direct answer

    As hyperscaler clusters scale toward multi-gigawatt installations, physical infrastructure constraints like heat rejection and chip-to-chip bandwidth have become primary deployment hurdles. Vendors addressing liquid cooling loops and signal conditioning capture unhedged margin expansion as data center power densities exceed traditional air-cooling limits. Astera Labs benefits directly from high-speed PCIe and CXL connectivity requirements across server racks, while Modine supplies purpose-built thermal systems. Flex serves as the scaled assembly partner for customized power and compute hardware.
