ZutaCore launches liquid cooling for advanced Nvidia chips

ZutaCore has launched a liquid cooling system called HyperCool that can handle the forthcoming Nvidia GB200 Grace Blackwell superchip without modifications to the data center or the rack – a common requirement of liquid cooling.

Grace Blackwell is a gigantic chip with 400 billion transistors and five components: two Blackwell GPUs, a Grace CPU, and two I/O chips. Its power draw is believed to be over 1kW, making air cooling an extreme challenge.

ZutaCore claims to have the industry’s first dielectric cold plates to support this new platform, featuring the ability to cool 120kW of rack power with little or no modifications to current real estate, power, or cooling systems.

For contrast, air cooling taps out at about 30 kW and is no longer viable for cooling the system. And liquid cooling usually means some kind of piping has to be installed in the facilities, but ZutaCore claims that isn’t necessary with its system.

ZutaCore’s technology can cool the NVIDIA GB200 Superchip with a single cold plate, “delivering an industry-first waterless direct-to-chip liquid cooling solution,” said Erez Freibach, co-founder and CEO at ZutaCore, in a statement. “This breakthrough frees AI data center owners and operators from the risks associated with water-based cooling, empowering them to deploy the processing power needed for compute-intensive workloads like generative AI without the fear of leakages.”

ZutaCore says HyperCool can be implemented in new or existing data centers to deliver 10 times more computing power, a 50% reduction in total cost of ownership, 100% heat reuse, and reduced CO2 emissions.

There is a small but growing ecosystem of servers certified to work with HyperCool, including models from Dell Technologies, ASUS, Pegatron, and SuperMicro. 

In addition to its offering for the GB200 Grace Blackwell Superchip, ZutaCore previously unveiled HyperCool support for older Nvidia H100 and H200 GPUs.

Separately, ZutaCore announced a strategic OEM agreement with UNICOM Engineering, a Dell Titanium Partner, to deliver warrantied HyperCooled AI servers for the H100 and H200 GPUs. ZutaCore also announced that a global AI-as-a-service provider has already chosen its HyperCool direct-to-chip liquid cooling for AI servers with deployments starting in Q3 2024.
