What's changing

The data centre's cooling.

AI servers produce more heat than air can remove, so data centres are moving to liquid cooling, with cold liquid piped right up to the chip. Vertiv, Johnson Controls, Trane Technologies and Carrier are racing to supply it, and their engineering is growing fastest where data centres are being built.
