Nvidia plans to adopt microchannel cold plate technology for its Rubin Ultra artificial intelligence processors to address rising power consumption and thermal management challenges. The company contacted Asia Vital Components, a Taiwanese thermal solution provider, to develop the cooling system that directs liquid coolant through microscopic channels embedded in copper plates attached directly to processor chips.

The technology reduces thermal resistance between the processor die and cooling fluid through localized convection. Nvidia originally intended to implement microchannel cold plates with the Rubin generation, but the accelerated product timeline forced suppliers to delay the transition until Rubin Ultra.

The shift from conventional liquid cooling reflects industry demands for advanced thermal solutions as power requirements increase with each processor generation. Microsoft announced a similar microfluidic cooling approach that places coolant inside or on the backside of silicon chips.

Nvidia requires more efficient cooling methods to support complex rack-scale systems and maintain its rapid product development schedule. The architectural improvements in next-generation processors necessitate thermal management solutions beyond traditional cooling approaches.
