As artificial intelligence continues its explosive growth, a critical challenge threatens to derail progress: the massive AI heat problem. With Nvidia’s upcoming Rubin GPUs expected to draw up to 600 kilowatts per rack – nearly double the power of today’s fastest EV chargers – traditional cooling methods are hitting their limits. One innovative startup, Alloy Enterprises, believes the answer lies in an unexpected place: stacks of metal.
The Growing AI Heat Problem in Modern Data Centers
The AI heat problem has become increasingly urgent as computational demands skyrocket. When Nvidia announced its Rubin series GPUs in March, the industry faced a sobering reality: data center racks are becoming power-hungry monsters. At 600 kilowatts, these systems generate enough heat to challenge even the most advanced cooling infrastructure. The situation becomes even more critical when you consider that peripheral chips – memory and networking hardware – account for about 20% of a server’s cooling load.
Innovative Data Center Cooling Breakthrough
Alloy Enterprises has developed a revolutionary approach to data center cooling that could transform how we manage heat in AI infrastructure. Their technology uses additive manufacturing to create solid cooling plates from copper sheets, specifically designed for GPUs and supporting components. Unlike traditional methods, their process creates seamless cold plates that can withstand the high pressures of liquid cooling systems.
Key Advantages of Alloy’s Liquid Cooling Technology
- •35% better thermal performance than competitors
- •Seamless construction eliminates potential leak points
- •Ability to create features as small as 50 microns
- •Uses corrosion-resistant copper for optimal heat conduction
- •More cost-effective than 3D printing alternatives
Advanced Liquid Cooling Technology Explained
What makes Alloy’s liquid cooling technology unique is their proprietary ‘stack forging’ process. Instead of traditional machining or 3D printing, the company takes sheets of metal and bonds them using heat and pressure. This diffusion bonding technique creates cold plates that are essentially single blocks of metal with no seams and no porosity issues. The result is a product that maintains raw material properties while offering superior thermal performance.
| Cooling Method | Thermal Performance | Cost Efficiency | Reliability |
|---|---|---|---|
| Traditional Machining | Standard | High | Medium (seam issues) |
| 3D Printing | Good | Low | Medium (porosity) |
| Alloy Stack Forging | Excellent (35% better) | Medium | High (seamless) |
Revolutionary GPU Cooling Solutions
The demand for effective GPU cooling solutions has never been higher. As racks approach 480 kilowatts on their way to 600 kilowatts, engineers must find ways to liquid cool everything from RAM to networking chips. Alloy’s approach addresses this challenge head-on with cold plates capable of squeezing into tight spots while handling the demanding requirements of modern AI hardware.
Alloy Enterprises: The Company Behind the Innovation
Founded by CEO Ali Forsyth, Alloy Enterprises initially developed their technology for aluminum alloys but quickly pivoted to copper as data center interest grew. The company’s manufacturing process involves cutting copper sheets with lasers, applying inhibitors to prevent unwanted bonding, and using diffusion bonding to create solid metal blocks. According to Forsyth, the response since their June product announcement has been overwhelming, with interest from “all the big names” in the data center industry.
