Key Takeaways

JetCool, a subsidiary of Flex, announced a strategic collaboration with Broadcom on March 11, 2026, to develop and mass-produce liquid cooling solutions for next-generation AI hardware. This partnership directly addresses the critical challenge of extreme heat generated by increasingly powerful AI processors, positioning both companies to capitalize on the expansion of high-density data centers.

Broadcom and JetCool have partnered to create liquid cooling for future AI XPUs.
Flex will provide global mass-production capabilities to manufacture the cooling solutions at scale.
The collaboration targets rising silicon power densities, which now reach sustained multi-kilowatt ranges per device.

Partnership Targets Multi-Kilowatt AI Chip Heat

JetCool, a liquid cooling specialist owned by Flex, announced on March 11, 2026, a new collaboration with semiconductor giant Broadcom. The partnership aims to deliver advanced liquid cooling for next-generation AI XPUs (Accelerated Processing Units). This move directly confronts the growing power demands from intensive AI training and inference workloads, which are pushing silicon power densities into sustained multi-kilowatt ranges per chip and creating a significant thermal bottleneck for performance.

Flex Deploys Manufacturing Scale for AI Supply Chain

The involvement of Flex (NASDAQ: FLEX) provides the industrial backbone for this technological initiative. By leveraging its global mass production capabilities, Flex will enable JetCool's innovative cooling designs to be manufactured at the scale required by major data center operators and hardware providers. This solidifies Flex's strategic position as a critical manufacturing partner within the high-growth AI hardware supply chain, moving beyond assembly into specialized, high-value component production.

Broadcom Secures Path for Future AI Hardware

For Broadcom, this collaboration is a strategic move to de-risk its future product roadmap. By securing a scalable, high-performance liquid cooling solution for its upcoming AI XPUs, the company ensures its processors can operate at peak efficiency without thermal throttling. This gives Broadcom a competitive advantage in the high-performance computing market, allowing it to design more powerful and densely packed AI systems for the next wave of data center infrastructure.
