Nvidia's next-generation Blackwell processors are facing significant challenges with overheating when installed in high-capacity server racks, reports The Information. These issues have reportedly led to design changes and delays and raised concerns among customers like Google,

Apparently, rack suppliers have changed the rack designs at Nvidia’s request more than once. The Information first noted the issue. But Nvidia quickly pointed out to Reuters that design changes are part and parcel of developing high-end tech. The word is that the requested changes were designed to solve heat-related problems.

Speaking to DCD earlier this year, Ian Buck, Nvidia’s accelerated computing VP, said: "The fabric of NVLink, the spine, is connecting all those 72 GPUs to deliver an overall performance of 720 petaflops of training, 1.4 exaflops of inference."
