Microsoft introduces an innovative microfluidics method for cooling AI chips, achieving up to 65% reduction in maximum silicon temperature. This technology enhances efficiency in data centers by flowing coolant closer to the heat source through intricate channels on chip backs. Tested on Office cloud and AI GPUs, the technique supports overclocking without damage. "Efficiency is very important," states Rani Borkar, VP at Azure, underscoring this strategic move toward hardware optimization.
