flag Microsoft’s new microfluidic cooling tech slashes AI chip temps by 65%, boosting performance and efficiency.

flag Microsoft has developed a prototype microfluidic cooling system for AI chips that uses tiny channels etched directly onto the chip to circulate coolant, reducing peak temperatures by up to 65% compared to traditional methods. flag The technology, tested at its Redmond campus, enables higher performance, safer overclocking, and more efficient data center operations by allowing chips to run hotter without throttling. flag It supports advanced designs like 3D stacking and improves energy efficiency, potentially lowering grid demand and waste heat. flag The system is being integrated into Microsoft’s custom AI chips, including the Maia Accelerator and Cobalt CPU, and may benefit the broader industry. flag While still in development, it represents a major step toward solving AI hardware’s growing thermal challenges.
