Green Revolution Cooling (GRC), a startup specializing in immersion cooling for server hardware, will work with Intel to drive wider adoption of this technology in data centers. The multi-year partnership announced by the two companies involves working with data center customers to develop and implement advanced immersion cooling techniques for future data centers. The two companies plan to test the security and reliability of the technology for immersion-cooled rack servers powered by Intel Xeon Scalable processors.

Immersion cooling is as the name suggests.

Instead of covering the CPU and other chips with heatsinks (radiators and fans), the entire motherboard is immersed in a liquid bath that keeps all hardware cool. Obviously, the bath is not water, but a non-conductive fluid that won’t burn out the electronics.The partners argue that immersion-cooled racks powered by Intel Xeon Scalable processors would perform better, but those are the GPUs and accelerators dedicated to the artificial intelligence that could really benefit from immersion, because they are the ones that heat up the most.

Aside from the research aspect, the two companies plan to work together to spread awareness of the benefits of liquid immersion cooling technology by hosting webinars, producing podcasts, and publishing white papers. “Our collaboration with GRC aligns with Intel’s goal of supporting cutting-edge technologies that can deliver increased efficiency and density for data center deployments and edge deployments,” said Mohan Kumar, senior fellow, in a statement. at Intel. “Through this collaboration, we are able to provide customers with customized solutions to meet their compute and cooling needs, and ensure data centers operate in a more environmentally friendly manner,” said- he added. Green Revolution Cooling’s partnership with Intel in immersion cooling is not the first of its kind for the start-up. In August 2021, GRC announced a similar agreement with European immersion cooling start-up Submer to develop immersible systems based on Xeon Scalable.

A solution that is gaining popularity

This year could well be the breakout year for immersion cooling. Last year, Microsoft has already distinguished itself with initiatives in this area. In particular, the supplier launched an extensive immersion cooling experiment in its data center in Quincy (Washington), to find that, thanks to immersion cooling, the servers consumed 5 to 15% less energy. Microsoft used DataTanks dip tanks made by Chinese hardware vendor Wywinn. Last year, Wywinn received $10 million in funding to launch LiquidStack, a subsidiary responsible for selling DataTanks units. Microsoft was one of the early adopters of DataTanks, which undoubtedly helped spread the word. With Intel’s involvement, it probably won’t be long before hyperscalers (AWS, Google) and other chipmakers (AMD, Nvidia) embrace immersion cooling religiously. The chances are therefore strong to see a breakthrough in technology this year.
