Microsoft used AI to invent a safer coolant — and dunked a PC in it

Microsoft says it used its personal agentic reasoning AI mannequin to assist develop and synthesize a brand new immersion fluid for PC cooling—after which confirmed that it labored by dunking a PC motherboard right into a vat of it.

John Hyperlink, Microsoft’s principal program supervisor for product innovation, closed out Microsoft’s Construct developer keynote by displaying off how Microsoft innovated a brand new immersion cooling know-how utilizing Copilot AI with none PFAS (or what’s generally known as “without end chemical substances”).

PC boards and server racks will be cooled by air, by water, or by connecting steel warmth exchangers with fluid-filled tubing that thermally routes the warmth of a processor to the skin world. Immersion cooling is an excessive instance of this, which makes use of electrically non-conductive fluids that encompass the whole board. Primarily, the whole board is submerged. Water can’t be used as a result of it might quick out the system, so PFAS can be utilized as a substitute—however PFAS presents environmental and well being hazards.

Hyperlink used what Microsoft calls Microsoft Discovery, an agentic analysis system. Agentic AI is Microsoft’s subsequent large factor, and your one-on-one interactions with Copilot will quickly give strategy to managing particular person AIs that autonomously carry out specialised duties.

In keeping with Microsoft, the mannequin makes use of each proprietary information in addition to exterior analysis to attempt to develop relationships between the information. In Hyperlink’s demonstration, it used each a “Data Base” agent in addition to a specialised chemistry agent. The instance tried to exclude any proposed molecules that might violate the PFAS circumstances, and that fell inside a sure dielectric vary and boiling factors.

You’ll be able to watch Hyperlink’s Microsoft Construct 2025 keynote closeout to see what he found, but it surely seems to be a member of the alkene household.

Extra to the purpose, Hyperlink mentioned that the invention was promising sufficient that Microsoft synthesized sufficient of it to dunk a motherboard and PC processor inside a container of the stuff, after which ran Forza Motorsport to show that it labored.
