Nvidia ditches traditional liquid cooling for its Rubin Ultra AI chips, adopting microchannel cold plate technology for enhanced thermal efficiency. Brackly News explores this bold shift and what it means for AI data center hardware.
🔥 Nvidia Introduces Microchannel Cooling for Rubin Ultra Chips
In a bold engineering shift, Nvidia is transforming how it cools its next-gen Rubin Ultra AI chips, opting for a microchannel cold plate system — a move that ditches conventional liquid cooling in favor of direct-to-chip thermal design.
According to early leaks and industry whispers, the cooling system will use microscopic channels inside copper cold plates, allowing coolant to flow directly over the GPU die. This reduces thermal resistance, improves heat dissipation, and enables Rubin Ultra chips to maintain higher performance per watt, even under massive AI workloads.
🧠 Why This Matters for AI Hardware and Data Centers
Rubin Ultra is set to follow Nvidia’s Blackwell architecture, but it’s expected to be significantly more power-hungry. This puts immense pressure on traditional cooling systems, which are no longer sufficient at this scale.
The microchannel design is inspired by direct-die cooling used by high-end PC enthusiasts but scaled for enterprise-grade rack systems. This leap in thermal innovation may be critical to unlocking Rubin Ultra’s full potential without performance throttling.
🏭 Who’s Involved: Asia Vital Components (AVC) and Industry Trends
Sources suggest Nvidia is collaborating with Asia Vital Components (AVC) — a leading Taiwanese manufacturer of cooling solutions. The company has extensive experience in microchannel plate fabrication and system-level thermal solutions.
This shift also mirrors a broader industry trend: Microsoft is testing microfluidic cooling, running coolant through tiny channels inside silicon dies — another example of advanced thermal engineering going mainstream.
