Nvidia has announced its new plan for reducing the energy use of data centers crunching massive amounts of data or training AI models: liquid-cooled graphics cards. The company announced at Computex that it’s introducing a liquid-cooled version of its A100 compute card, and says that it consumes 30 percent less power than the air-cooled version. Nvidia’s also pledging that this isn’t just a one-off, it’s already got more liquid-cooled server cards on its roadmap, and hints at bringing the tech to other applications like in-car systems that need to keep cool in enclosed spaces. Of course, Tesla’s recent recall for overheating chips shows how tricky that can be, even with liquid cooling.

According to Nvidia, reducing the energy needed to...
