Nvidia Customers Worry About Snag With New AI Chip Servers

Nvidia is grappling with new problems related to its much-anticipated Blackwell graphics processing units for artificial intelligence: how to prevent them from overheating when connected together in the customized server racks it has designed.

In recent months, Nvidia has asked its suppliers to change the design of the racks several times as it has tried to overcome the overheating problems, according to Nvidia employees who have been working on the issue, as well as several customers and suppliers with knowledge of it. Word of the repeated design changes has sparked anxiety among customers about a potential delay in when they will be able to use the racks.
