NVIDIA’s GB300 NVL72 racks need $50,000 in liquid cooling
Nvidia requires nearly $50,000 worth of thermal management equipment for each GB300 Blackwell Ultra NVL72 server rack to control temperatures from 72 graphics processors and 32 Grace central processing units that consume more than 100 kilowatts under peak loads. Morgan Stanley analysis reveals that air circulation cannot handle the 1,400-watt rating of individual graphics chips, forcing the company to deploy liquid systems with coolant flowing through metal cold plates mounted atop processor dies. Each of the 18 compute modules costs approximately $2,260 for thermal components, while nine network switch sections add roughly $1,020 apiece.
Facilities installing these systems must construct supporting infrastructure such as coolant distribution equipment, plumbing networks, and chillers to expel thermal energy through building climate control systems. The method enables denser configurations in artificial intelligence data centers where real estate and electricity carry premium prices. Future Vera Rubin NVL144 platforms with double the graphics processor count will demand an estimated 17 percent increase in cooling investments to about $55,710 per installation, according to financial firm projections. The evolution reflects growing engineering obstacles as chip performance advances.
