Elon Musk's Texas Tesla Gigafactory is expanding to contain an AI supercomputer cluster, and Supermicro's CEO is a big fan of the cooling solution. Charles Liang, founder and CEO of Supermicro, took to X (formerly Twitter) to celebrate Musk's use of Supermicro's liquid cooling technology for both Tesla's new cluster and xAI's similar supercomputer, which is also on the way.
