During the Token 2049 event on September 19, 2024, Bitmain unveiled the U3S21EXPH, boasting an impressive 860TH/s , the highest for a single miner. It’s Bitmain’s first machine to feature a 3U server design and will be available for delivery in the second quarter of 2025. We were honored to participate in early prototype testing, installing the first units for a client. Curious about cooling such a powerful machine? We’ll share our experience and insights from this unique project.
