The system is the product of an extended joint research project between ETH and IBM scientists, focused on chip-level water-cooling. It also encompasses a concept for “water-cooled data centers with direct energy re-use” proposed by scientists at IBM’s Zurich Lab.
"Although the idea of using warm water for cooling might sound strange, the testing results are quite promising. It was discovered that warm water allows the processors of the supercomputer to work properly well below the highest point of allowed operating temperature. According to the developers, the new system cools processors "4,000 times more efficiently than air", reports Gizmag. "
