Data Center Frontier: Microsoft Tests Immersion Cooling Tech from Bitcoin Mining for its Cloud Servers

Microsoft is seeking better ways to manage powerful new AI hardware in its cloud computing operation, and focusing on immersion cooling technology used in bitcoin mining as the most promising technology for future high-density data centers.

Microsoft showed off a cooling lab where it is cooling servers inside a two-phase immersion system from LiquidStack (formerly Allied Control), which uses the design to support power densities of up to 250 kW per rack. Immersion can deliver exceptional power efficiency because it uses sealed tanks that don’t require the raised floors or room-level air cooling found in most commercial data centers.
