Intel partners with Vertiv to develop two-phase liquid cooling in Gaudi3 AI accelerator

Intel's new Gaudi3 AI accelerator is set to have two-phase liquid cooling developed in partnership with Vertiv. The systems will have a pumped two-phase (P2P) cooling system designed to remove up to 160kW of heat, using water from 17°C up to 45°C (62.6°F to 113°F). An alternative for air-cooled data centers up to 35°C (95°F) will work up to 40kW of heat load.

Heiko Ebermann, senior program manager rack cooling, EMEA at Vertiv said, "Vertiv has high internal standards for the sustainability of its products. It goes without saying that we comply with all environmental regulations - including new technologies such as immersion cooling with evaporative cooling. Vertiv will not use PFAS substances."

The company mentioned that the Vertiv systems will not use PFAS. However, its replacement remains unclear. "Vertiv is convinced that there are alternatives to cooling systems using PFAS substances and is currently evaluating alternatives," said Ebermann.

Update: An earlier version of this story included a statement from Vertiv saying the company would not use PFAS substances. Vertiv has now withdrawn that statement, but declined to say what coolant it will use.

The company says it will use "low GWP engineered fluids that are compliant with applicable EU regulations," adding that it "continues to research and evaluate innovative technologies to support customer demand and enable customer sustainability objectives."
