For a decade or more, we’ve all been hearing “this is the year we’ll see liquid cooled data centers.” And every year, we’ve seen a few liquid cooled HPC clusters, or we’ve seen it in small-scale deployments, but we’ve never seen liquid cooling tip over into a mainstream data center technology. 

But if you follow the industry, since 2022, you’ve probably heard more about liquid cooling than ever before, and you’ve watched industry leaders like Meta announce that they’re redesigning their data centers to use liquid cooling, at scale.

Well, to put it simply, the data center industry is experiencing unprecedented opportunity to change the designs and economics of running their data centers by shifting toward liquid cooling as rapidly as possible.

The opportunity is all due to physics. Liquid cooling is a more efficient and environmentally friendly way to cool data centers than air cooling, because, compared with air, water is 23.5 times more efficient at transferring heat, and it has four times the heat carrying capacity. That physical efficiency and capacity translates into new opportunities for operational efficiency and capacity.

The higher heat carrying efficiency and capacity of liquid cooling is critical to the future of the industry. Today’s server innovation, intended to power intensive workloads like Generative AI, are forcing data center operators to consider a future where a 1U server will consume 1kW, 2kW, or even 3kW — generating 40-120kW of heat per rack — which simply cannot be handled with air.
