""We'll have fluid that comes up and [then] shower down, or trickle down, onto a component," says Jonathan Ballon, chief executive at liquid cooling firm Iceotope. "Some things will get sprayed." In other cases, the industrious gizmos recline in circulating baths of fluid, which ferries away the heat they generate, enabling them to function at very high speeds, known as "overclocking"."
"Currently, demand for data centres is booming, driven partly by the growth of AI technologies. But the huge amounts of energy and water that many of these facilities consume mean that they are increasingly controversial. More than 200 environmental groups in the US recently demanded a moratorium on new data centres in the country. But there are some data centre firms that say they want to reduce their impact. They have another incentive."
Data-centre computer chips run continuously at high speeds and generate intense heat that requires advanced cooling. Liquid cooling techniques include fluid that showers or trickles onto components, spraying select parts, or immersing hardware in circulating baths to carry heat away. Effective liquid cooling allows constant overclocking without risk of burning out servers. Waste heat can be reused for heating buildings, laundries and pools. Cooling failures can cause major outages for critical services. Rising demand for data centres, driven by AI, raises energy and water concerns and has prompted calls for moratoria, while operators seek to reduce environmental impacts.
