Nov 17 (Reuters) - Nvidia's ( NVDA ) new Blackwell AI

chips, which have already faced delays, have encountered

problems with accompanying servers that overheat, causing some

customers to worry they will not have enough time to get new

data centers up and running, the Information reported on Sunday.

The Blackwell graphics processing units overheat when

connected together in server racks designed to hold up to 72

chips, the report said, citing sources familiar with the issue.

The chipmaker has asked its suppliers to change the design

of the racks several times to resolve overheating problems,

according to Nvidia ( NVDA ) employees who have been working on the

issue, as well as customers and suppliers with knowledge of the

issue, the report said without naming the suppliers.

"Nvidia ( NVDA ) is working with leading cloud service providers as

an integral part of our engineering team and process. The

engineering iterations are normal and expected," a company

spokesperson said in a statement to Reuters.

In March, Nvidia ( NVDA ) unveiled Blackwell chips and had earlier

said they would ship in the second quarter before encountering

delays, potentially affecting customers such as Meta Platforms ( META )

, Alphabet's Google and Microsoft ( MSFT ).

Nvidia's ( NVDA ) Blackwell chip takes two squares of silicon the

size of the company's previous offering and binds them into a

single component that is 30 times speedier at tasks like

providing responses from chatbots.
