Nvidia’s “GB200 systems are the most advanced computers ever created” and “integrating them into a diverse range of data center environments requires co-engineering with our customers,” an Nvidia spokesperson told The Information. “The engineering iterations are normal and expected.”

The server rack Nvidia designed for Blackwell —which can connect up to 72 GPUs at a time—is reportedly causing the overheating issue. Nvidia has repeatedly redesigned the racks, which could result in GPU server shipments being delayed and new Google, Microsoft, or Meta data centers may not be able to open on schedule.

Blackwell GPUs are overheating when connected in custom server racks, according to a report from The Information.
