Diamond Cold Plates Commercially Launched, Bringing A New Cooling Solution For AI Servers

Against the backdrop of surging computing power for large model training and supercomputing clusters, the heat dissipation bottleneck caused by high-power GPUs has become a core factor restricting the performance of AI servers. Conventional copper cold plates have hit performance limits, while liquid cooling solutions based on diamond composite materials have moved beyond laboratory trials and small-scale pilot tests to enter large-scale commercial use, offering an efficient new approach for next-generation high-end computing hardware.

 

Wiwynn, a subsidiary of Wistron and a key ODM partner of NVIDIA, announced that it would globally debut a diamond composite server cold plate tailored for NVIDIA's new Vera Rubin AI platform at COMPUTEX 2026 in Taipei. This milestone marks the full commercialization of diamond liquid cooling technology for mass-produced AI servers.

 

Diamond composite materials boast two irreplaceable advantages over mainstream copper cooling materials. First, they deliver vastly superior thermal conductivity: high-quality synthetic diamond conducts heat 4 to 5 times faster than copper. It rapidly dissipates massive heat generated by high-heat-flux chips such as GPUs and CPUs, fundamentally resolving issues including performance throttling, system lagging and thermal throttling triggered by excessive temperatures. Second, diamond composites are extremely lightweight, with only one-third the density of copper. While maintaining equivalent cooling capacity, they drastically cut the overall weight of AI server racks, streamline equipment layout design in data centers and greatly improve long-term operational stability.

The industrialization of diamond liquid cooling is accelerating worldwide. US firm Akash Systems has rolled out multiple commercial breakthroughs this year. In February, it delivered the world's first liquid-cooled NVIDIA H200 GPU servers equipped with diamond cooling technology. In March, it launched a matching liquid cooling server for AMD Instinct MI350X GPUs, with mass production outsourced to MiTAC. Practical operational data shows that data centers adopting diamond liquid cooling see boosted overall operating efficiency, alongside reduced energy consumption and lower Total Cost of Ownership (TCO).

 

 

Industry analysts note that as power consumption per server rack keeps rising, air cooling is gradually phased out of high-end computing scenarios, and standard copper liquid cooling plates are approaching their performance ceiling. Diamond composite cooling stands out as the optimal solution to address heat dissipation challenges for high-heat-flux computing hardware. With hardware suppliers including Wiwynn, Akash and MiTAC rolling out mature mass-production solutions, diamond cold plates are poised to become the standard cooling configuration for next-gen high-end NVIDIA and AMD AI servers. The technology will help data centers balance higher computing performance and lower energy costs, accelerating the global upgrade of AI infrastructure.
