Hi ZutaCore has today announced OmniTherm™, a single-slot cold plate that enables waterless two-phase liquid cooling for servers built with NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs. The launch addresses a growing challenge for enterprise and cloud operators deploying AI infrastructure. While PCIe GPU servers remain attractive because they integrate easily into existing environments, rising GPU power levels are making air cooling increasingly difficult—limiting accelerator density, increasing fan power consumption, and raising the risk of thermal throttling during sustained workloads. The announcement comes ahead of NVIDIA GTC 2026, where ZutaCore will demonstrate OmniTherm cooling the NVIDIA RTX PRO 6000 Blackwell Server Edition GPU. Please find the full press release below. If you'd like additional information, or comments from the ZutaCore team, just let me know.Regards, Ethan
ZutaCore Brings Two-Phase Cooling to PCIe GPUs, Maximizing AI Performance in Enterprise and Cloud Servers Built with NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs OmniTherm™ delivers single-slot, waterless two-phase cooling to increase PCIe GPU density and reduce operational burden at scale .
Foster City, CA - March 16, 2026 - ZutaCore®, a leader in waterless, direct-to-chip, two-phase liquid cooling, today announced that its OmniTherm™ cold plate enables waterless two-phase cooling for manufacturers building servers with the NVIDIA RTX PRO 6000 Blackwell Server Edition GPUs in a single-slot PCIe form factor - supporting full-power operation in standard enterprise and AI cloud server environments.
As AI inference expands rapidly across enterprise and cloud environments, PCIe GPU servers have become a preferred platform because they are easy to deploy, scale, and integrate into existing infrastructure. As GPU power rises, however, air cooling can become a limiting system factor - restricting density, driving up fan power, which in turn increases the risk of thermal throttling during sustained workloads.
OmniTherm removes these barriers by enabling a transition to two-phase liquid cooling without introducing water inside the server. The single-slot design allows operators to increase accelerator density in standard server architectures while capturing heat into a liquid loop, reducing reliance on extreme fan speeds that can create excessive noise, waste power and cause challenging operating conditions in the data center.
“Enterprise and cloud operators want the flexibility of PCIe GPUs, but they also need density and sustained performance as power levels rise,” said My D. Troung, CTO of ZutaCore. “OmniTherm delivers waterless two-phase cooling in a single-slot form factor, helping data centers increase accelerator density while maintaining stable thermals for 24/7 AI workloads.”Built for Always-On AI Operations Production AI workloads - especially inference - are rarely steady. They fluctuate constantly, creating thermal swings that can impact performance and reliability. ZutaCore’s two-phase approach is designed to respond rapidly to changing workloads, helping data centers maintain predictable performance under dynamic utilization. Designed to Protect Long-Term Infrastructure Investment For data center operators, reliability is as critical as raw performance. OmniTherm is designed to cool not only the GPU die, but also critical surrounding components including CPU and next-generation high-bandwidth memory. This broader cooling coverage supports long-duration, bandwidth-intensive AI workloads and helps reduce thermal stress that can impact long-term system stability. Operational Advantages at Scale As racks push into higher power levels, the operational cost of air cooling rises quickly, with higher fan energy consumption and growing acoustic and facility pressures. OmniTherm uses a sealed, non-conductive dielectric fluid system that enables efficient heat capture without facility water in the server. This helps reduce cooling overhead, supports improved operating conditions for data center personnel, and provides a practical path to scaling PCIe-based AI deployments. NVIDIA GTC 2026 Showcase ZutaCore is a Silver Sponsor of NVIDIA GTC 2026 and will exhibit at booth #125, featuring OmniTherm cooling the NVIDIA RTX PRO 6000 Blackwell Server Edition. ZutaCore will also showcase an interactive 3D experience of its HyperCool® two-phase cooling solution, developed in collaboration with Smart Spatial. CTO My D. Troung will deliver a theater presentation on two-phase cooling architectures designed to support high-density PCIe AI deployments. Scalable Cooling Operations with HyperCool Cloud ZutaCore is also introducing HyperCool® Cloud, a secure, cloud-native operations platform designed to help data centers manage liquid cooling infrastructure with greater visibility and lower operational risk. HyperCool Cloud provides near real-time CDU telemetry, fleet-level monitoring, and alarm-to-resolution workflows, helping operators streamline service response and strengthen uptime management as deployments scale across sites and fleets.
