Akash Systems Deploys Diamond-Cooled NVIDIA GPUs

- Akash Systems' core innovation is a patented Gallium Nitride (GaN)-on-Diamond material, which places the heat-generating transistor within nanometers of a synthetic diamond substrate, the most thermally conductive material known. - The company was founded in 2016 by Felix Ejeckam and Ty Mitchell, with Ejeckam being the inventor of the GaN-on-Diamond technology. - In November 2024, Akash Systems secured a non-binding agreement for up to $18.2 million in direct funding from the U.S. Department of Commerce through the CHIPS and Science Act. This funding is part of a larger $121 million joint investment to develop a 40,000-square-foot cleanroom facility in West Oakland, California. - Before its GPU cooling applications, Akash focused on using its technology for satellite communications, claiming its radios could offer 5-10 times faster data rates and a 50% smaller form factor. Pixxel, a hyperspectral imagery company, is a customer, using the diamond cooling technology for thermal management in its satellite payloads. - The recipient of the servers, NxtGen AI Pvt Ltd, is a Bangalore-based private limited company incorporated in September 2022, operating in the information technology sector. - The global data center cooling market was valued at over $26 billion in 2025 and is projected to reach over $128 billion by 2033, with liquid cooling solutions seeing the fastest growth due to the demands of high-density computing and AI. - Traditional air cooling in data centers is becoming insufficient as AI workloads can push rack power densities from a traditional 5-8 kW to between 30 and 120 kW per rack. - Akash claims its technology can reduce a GPU's hot-spot temperature by 10 to 20 degrees Celsius, which can translate into millions of dollars in cooling cost savings for a data center with hundreds of servers.
