CASTROL this cooling method dramatically decreases energy consumption.“ You cut down on everything. The only thing you really operate is just the pumps on the tanks, and those pumps are not very strong,” he says.
“ Data centres themselves consume a lot of power. And from the traditional format of using air cooling to get the most efficient cooling method, you also need to consume a lot of water.”
These resource demands inevitably create environmental challenges, as Stephen explains:“ From the power and water perspective, you have a lot of impact, and then you also have land use as well.”
Immersion cooling emerges as a critical solution during a turbulent time for the industry, as AI workloads threaten to continue increasing compute demand. The heat generated by these high-performance computing( HPC) components has outpaced what traditional cooling methods can deliver within the data centre.
“ AI is driving a lot of changes as it requires high-performance CPUs and GPUs, which generate a lot of heat,” says Sung Kim, Global Head of Data Centre Liquid Cooling Solutions at Castrol.“ The data centre industry is mostly on air cooling design, which can cool up to only 50 kilowatts( kW), but that is not
