Born-In-Immersion Hardware

Overview

Born-In-Immersion Hardware refers to IT equipment designed natively for fluid immersion environments rather than converted from air-cooled designs. As of 2025, no commercially available server is designed from the ground up for immersion; all deployed immersion servers are air-cooled designs that have been modified — fans removed, thermal interface materials replaced, and non-compatible materials swapped — to survive submersion in dielectric fluid. This conversion approach introduces a class of failure modes that purpose-built hardware would eliminate by design, and is widely regarded as a critical gap for large-scale, long-term immersion deployment.

The absence of born-in-immersion hardware means that every current Immersion Cooling deployment inherits air-cooling design assumptions: plastic materials selected for air-cooled thermal performance rather than fluid compatibility, connector sealing designed for humidity rather than fluid submersion, and mechanical assemblies designed for serviceability in air. OCP workstreams including the ITE ACT (Advanced Cooling Technologies) workstream are working to define specifications that would enable server OEMs to design native immersion products. The Material Compatibility Testing challenges that conversion-based deployments face would largely be addressed by hardware designed natively for the fluid environment.
