Cooling Technology

Cold-plate liquid cooling and immersion cooling solve the same heat problem in different ways. This guide compares server compatibility, serviceability, facility design, water use and operations to help data-center teams choose the right architecture.

Direct-to-chip (D2C) cooling delivers coolant directly to GPU and CPU heat sources through precision cold plates, enabling rack densities of 80-120kW while maintaining chip junction temperatures 20-30°C below air-cooled levels. This technical guide covers the engineering, deployment, and operational considerations.

While PUE measures energy efficiency, Water Usage Effectiveness (WUE) measures how much water a data center consumes per kilowatt-hour of IT energy. As regulatory scrutiny intensifies and water scarcity becomes a global concern, WUE is emerging as the next critical metric for data center operators and investors.

This article examines the engineering differences between air cooling and hydro cooling in high-density ASIC deployments — covering heat dissipation capacity, operational stability, energy efficiency, and long-term infrastructure scalability. For operators evaluating cooling architecture for new or expanding high-density compute data centers, understanding these differences has direct implications for uptime, hardware longevity, and cost of operation.
