Best Supercomputing Cooling Innovation at ISC | Nimbus | ZutaCore

It’s a wrap for the ISC High Performance 2025 Conference and Exhibition in Hamburg, Germany…..and ZutaCore^® came home with the Gold! It’s HyperCool^® technology was awarded a Nimbus Innovation Award for “Best Supercomputing Cooling Innovation.” With only 16 Nimbus awards given at this year’s ISC, ZutaCore was in good company next to Intel, AMD, NVIDIA, IBM and others!

ZutaCore won this award for its groundbreaking HyperCool two-phase, direct-to-chip liquid cooling technology, which enables data centers and AI factories to bring megawatt compute power into their new and existing facilities in the most energy efficient, cost effective and sustainable way. With high-performance GPUs pushing traditional cooling methods to their limits, HyperCool has emerged as the most effective liquid cooling technology for managing the heat, boosting sustainability, and unlocking more power for demanding AI workloads.

The Nimbus Alliance organizes the prestigious Nimbus Innovation Awards, a collaborative initiative formed by four of Europe’s most respected B2B technology publications: PRONETIC (Spain), XX / Pro (Germany), Technology Insider Pro (Netherlands), and EDGE9 (Italy). 124 technology brands took part in the award event at ISC 2025, and the editorial team selected the winners.

More ZutaCore Highlights from ISC

Winning an award was not the only highlight during ISC. During the first day of the show, ZutaCore’s CRO Andreas Keiger opened the exhibit hall with an inspiring overview on how HPC and AI data centers can increase compute performance, reduce energy costs, and enable energy reuse—all powered by ZutaCore’s waterless liquid cooling solutions.

ZutaCore technology was also showcased throughout the show floor with amazing demos at our partner booths such as Boston Server & Storage Solutions GmbH and Compal Server. In fact, Compal generated quite the buzz with its ZutaCore waterless liquid cooling demo for the AMD Mi325x GPU in their advanced AI server.

A special highlight of the show was a visit from our customer, the University of Münster, one of the largest universities in Germany. By deploying HyperCool, the University’s Center for Information Technology (CIT) has gained unmatched computing power, reduced energy costs, and eliminated the risk of water leakage.

The University of Münster’s adoption of ZutaCore’s HyperCool solution exemplifies the transformative potential of advanced liquid cooling in higher education and research.

The HyperCool Advantage

ZutaCore’s HyperCool is an innovative, waterless, two-phase, direct-to-chip cooling technology designed to manage the temperature of high-performance processors and AI GPUs. Key advantages of HyperCool include:

• Requires No Water – The dual-phase pool boiling approach uses heat transfer fluid to remove the heat from the chips via liquid-to-vapor phase change.
• Lowers Energy Costs – HyperCool delivers 10-20% better energy efficiency with dynamic cooling, smaller pumps, and no performance degradation over time. It has been proven to cool the hottest chips of 2,800 watts with a data center PUE (power usage effectiveness) as low as 1.05-1.07 while increasing compute density.
• Enables Higher Server Densification – HyperCool allows for higher server densification needed in AI factories, consuming up to 50% less space than air-cooled data centers and up to 75% less space than immersion cooling.
• Allows for Heat Reuse – HyperCool enables telecom providers to harness the heat being generated from their AI factories for heating adjacent offices, other parts of the data center, or nearby schools, office buildings, and swimming pools. And since electrical capacity is often already at maximum, the power savings from not using heat pumps can be redirected to the compute infrastructure, generating more revenue for AI factories.
