Akash Systems, Inc., a developer of Diamond Cooling® technology, has delivered what it describes as the world’s first diamond-cooled GPU servers to NxtGen AI Pvt. Ltd., India’s largest sovereign cloud provider. With this deployment, a new chapter in AI infrastructure has been opened.

The rollout features NVIDIA H200 GPU servers integrated with Akash’s proprietary cooling technology. According to the company, the systems rank among the most energy- and capital-efficient of their kind. Performance gains of up to 15 percent in GPU compute and FLOPs per watt have been projected per server. Notably, these gains are expected even in data centers operating in temperatures as high as 50°C.

By contrast, most conventional data centers operate between 24°C and 29°C. Therefore, performance is often constrained by heat. With Diamond Cooling®, efficient operation in hotter environments has been enabled, which in turn reduces total cost of ownership and improves Power Usage Effectiveness.

Tackling AI’s Thermal Challenge

As AI workloads expand, thermal management has become a central infrastructure challenge. Consequently, operators have faced increasing pressure to prevent overheating while maintaining performance.

To address this constraint, Akash Systems uses synthetic diamond, widely recognized as the most thermally conductive material available. Heat is extracted up to five times faster than with copper, the current industry standard. By embedding diamond into the GPU cooling stack, excess heat is dissipated more efficiently.

Importantly, the technology complements existing air and liquid cooling systems rather than replacing them. As a result, sustained peak performance can be maintained during demanding training and inference workloads. Thermal throttling, which often limits compute output, is significantly reduced.

Dr. Felix Ejeckam, Co-Founder and CEO of Akash Systems, said the technology tackles two major constraints in AI infrastructure: energy and capital efficiency. He noted that even marginal compute improvements can shift competitive advantage, making a 15 percent gain particularly meaningful.

Designed for Extreme Conditions

Unlike traditional servers that rely heavily on refrigeration, Diamond-Cooled systems maintain full performance in high ambient heat. This capability allows data center operators to reduce cooling overhead while increasing compute density.

Additionally, FLOPs per watt can be improved, and reliance on energy-intensive cooling systems can be lowered. Server density can also be increased without a proportional rise in capital expenditure. As AI factories continue to scale worldwide, these efficiency gains are expected to play a critical role.

A.S. Rajgopal, CEO of NxtGen, said the company aims to build a high-performance cloud backbone for India’s AI innovators. By integrating Diamond Cooling® into its infrastructure, NxtGen expects to deliver improved competitiveness and cost efficiency.

From Space Technology to AI Infrastructure

Originally, Akash developed its diamond-based cooling systems for satellites, where air cooling cannot be used. The technology has already been validated in active space deployments. Now, it is being adapted for terrestrial AI data centers, where heat loads continue to rise.

Looking ahead, additional aftermarket Diamond Cooling® solutions are expected to be introduced for other NVIDIA platforms, including the upcoming Blackwell series. Through this expansion, broader adoption across next-generation AI infrastructure is anticipated.
