Warm Water Flowed Through Supercomputers to Cool Down Their Heat

From Scientific American:

Today's supercomputers run hot, thanks to power-hungry microprocessors that enable sophisticated scientific research and complex financial transactions to be performed in the blink of an eye. As these microprocessors have become smaller and more powerful over time , they are generating even more heat, a problem that data centers generally address expensively with air conditioning and chilled-liquid cooling systems.
