Microsoft develops breakthrough chip cooling method — microfluidic channels can cut peak temps by up to 65%, outperform conventional cold plates by up to 3x

Microsoft has developed a groundbreaking chip cooling method using microfluidic channels that can reduce peak temperatures by up to 65%, outperforming conventional cold plates by up to three times. The technology involves etching channels on the back of the chip to guide coolant to high-heat regions inside the chip, improving efficiency. The design mimics patterns found in nature to optimize thermal routing and uses a specific coolant fluid. While this method adds complexity and cost to chip manufacturing, Microsoft is preparing for full-scale production within its chip development pipeline. The cooling solution has been tested on servers running simulated workloads, demonstrating improved efficiency and performance.
