To Cool Datacenter Servers, Microsoft Turns to Boiling Liquid – Microsoft

“We are the first cloud provider that is running two-phase immersion cooling in a production environment,” said Husam Alissa, a principal hardware engineer on Microsoft’s team for datacenter advanced development in Redmond, Washington.

“Air cooling is not enough,” said Christian Belady, distinguished engineer and vice president of Microsoft’s datacenter advanced development group in Redmond. “That’s what’s driving us to immersion cooling, where we can directly boil off the surfaces of the chip.”

Microsoft investigated liquid immersion as a cooling solution for high-performance computing applications such as AI. Among other things, the investigation revealed that two-phase immersion cooling reduced power consumption for any given server by 5% to 15%.

The findings motivated the Microsoft team to work with Wiwynn, a datacenter IT system manufacturer and designer, to develop a two-phase immersion cooling solution. The first solution is now running at Microsoft’s datacenter in Quincy.
