Wiwynn Debuts Diamond-Cooled Servers at COMPUTEX

Wiwynn, a leading data center infrastructure provider under Wistron, is set to revolutionize server cooling at COMPUTEX 2026. The company will showcase advanced diamond composite cold plates designed for high-density AI deployments.

This innovation addresses critical thermal challenges in modern computing. By integrating diamond materials, Wiwynn aims to enhance heat dissipation while significantly reducing system weight.

Key Facts: Wiwynn's Thermal Breakthrough

• Material Innovation: Uses diamond composites with thermal conductivity far exceeding traditional metals.
• Weight Reduction: Diamond density (~3.5g/cm³) is less than half that of copper (~9g/cm³).
• Event Debut: New technology launches at COMPUTEX 2026 in Taipei next week.
• Industry Precedent: Akash Systems already shipped H200/MI350X systems using similar materials earlier this year.
• Future Scope: Technology may extend to chip-level packaging for even closer thermal management.
• Broader Portfolio: Includes NVIDIA Vera Rubin NVL72 racks and 800V HVDC solutions.

Diamond Composites Outperform Traditional Copper

Traditional server cooling relies heavily on copper due to its high thermal conductivity. However, copper presents significant drawbacks in weight and density. Wiwynn’s new approach leverages the unique properties of diamond to overcome these limitations.

Diamond offers exceptional thermal performance. Its ability to transfer heat away from processors is unmatched by conventional metals. This is crucial as AI chips generate increasing amounts of waste heat.

The weight advantage is equally important. Diamond composites weigh approximately 3.5g/cm³. In contrast, copper weighs about 9g/cm³. This difference reduces the overall load on data center structures.

Lighter cooling systems simplify installation and maintenance. They also lower shipping costs for large-scale deployments. As data centers scale, every kilogram saved contributes to operational efficiency.

Addressing High-Density AI Heat

Modern AI workloads push hardware to its thermal limits. Chips like the NVIDIA H200 require robust cooling solutions to maintain performance. Without effective heat removal, throttling occurs, slowing down training and inference tasks.

Wiwynn’s micro-channel cold plates integrate diamond directly into the cooling path. This design minimizes thermal resistance between the chip and the coolant. The result is faster heat extraction and more stable operating temperatures.

Akash Systems demonstrated the viability of this technology earlier this year. Their deployment of H200 and MI350X systems utilized diamond-based cooling. This real-world application proves the technology is ready for commercial adoption.

Comprehensive Product Lineup at COMPUTEX 2026

Beyond diamond cooling, Wiwynn will display a wide array of cutting-edge infrastructure. The exhibition highlights the company’s commitment to supporting next-generation AI architectures.

Attendees will see the NVIDIA Vera Rubin NVL72 rack. This system represents the latest in high-performance computing connectivity. It supports massive parallel processing required for large language model training.

AMD’s Helios rack will also be on display. This solution provides an alternative high-performance option for enterprises diversifying their hardware stack. Support for both major GPU vendors ensures flexibility for customers.

Advanced Storage and Power Solutions

Wiwynn is not just focusing on compute. The company will exhibit a 96-slot liquid-cooled SSD storage system. This setup supports NVIDIA SCADA architecture, ensuring fast data access for AI workflows.

Power efficiency remains a top priority. Wiwynn will showcase 800V HVDC cabinet solutions. High-voltage direct current distribution reduces energy loss during transmission. This is vital for lowering the total cost of ownership in large data centers.

Optical interconnects are another key focus. The CPO optical expansion cabinet enables higher bandwidth with lower latency. Co-packaged optics bring networking components closer to the switch ASICs, improving signal integrity.

For extreme thermal scenarios, Wiwynn introduces a 6kW double-sided liquid cold plate. This unit incorporates liquid metal TIM (Thermal Interface Material). Liquid metal offers superior thermal conductivity compared to traditional pastes, handling intense heat fluxes from dual-sided cooled modules.

Industry Context: The Race for Thermal Efficiency

The AI industry faces a growing thermal bottleneck. As chip power densities rise, air cooling becomes insufficient. Liquid cooling is no longer optional; it is mandatory for high-end AI clusters.

Major players are racing to optimize these systems. Companies like NVIDIA and AMD are designing chips specifically for liquid immersion or direct-to-chip cooling. Infrastructure providers like Wiwynn play a critical role in making these designs viable.

The shift toward diamond composites signals a maturation of the market. Early adopters experimented with various materials. Now, proven solutions like those from Akash Systems and Wiwynn are setting new standards.

Western data centers are particularly interested in these advancements. Energy costs in Europe and North America are rising. Efficient cooling directly impacts operational expenditures. Reducing the energy needed for HVAC systems can save millions annually.

Furthermore, sustainability goals drive innovation. Tech giants have committed to carbon neutrality. Lighter, more efficient cooling systems reduce the environmental footprint of data centers. This aligns with regulatory pressures in the EU and US.

What This Means for Data Center Operators

For IT leaders, Wiwynn’s announcement offers tangible benefits. The primary advantage is improved thermal headroom. Operators can pack more compute power into the same physical space.

This density increase accelerates AI training timelines. Faster cooling allows GPUs to run at peak frequencies for longer periods. Consequently, model development cycles shorten, providing a competitive edge.

Reduced weight also simplifies facility planning. Older buildings may not support heavy copper-heavy racks. Diamond composites allow for retrofits in existing infrastructure. This extends the life of legacy data center facilities.

Strategic Adoption Considerations

Businesses should evaluate their current cooling strategies. If relying on air cooling, the transition to liquid is urgent. Wiwynn’s solutions provide a pathway for this migration.

Consider the total cost of ownership. While diamond composites may have higher upfront costs, the savings in energy and space justify the investment. Calculate the ROI based on reduced power consumption and increased rack density.

Monitor the integration timeline. Wiwynn plans to expand this technology to chip-level packaging. This future evolution could further improve thermal performance. Stay informed about these developments to plan long-term infrastructure upgrades.

Looking Ahead: Future Implications

The introduction of diamond composite cooling marks a pivotal moment. It moves beyond incremental improvements to fundamental material science changes. This trend will likely accelerate over the next 3-5 years.

We can expect broader adoption across the industry. As manufacturing scales, costs for diamond composites will decrease. This will make the technology accessible to mid-tier data centers, not just hyperscalers.

The extension to packaging layers is particularly exciting. Integrating cooling directly into the chip package eliminates intermediate thermal barriers. This could unlock new levels of performance for next-gen AI accelerators.

Competitors will respond to Wiwynn’s lead. Other infrastructure providers must innovate to remain relevant. This competition drives further technological advancement and price reductions.

Ultimately, the goal is seamless thermal management. Users should not worry about overheating. The infrastructure will handle it automatically, allowing developers to focus on software and models.
