Nvidia faces order delays as Blackwell chips overheat
Microsoft, Amazon, Google and Meta have cut back on Nvidia Blackwell purchases due to technical issues.

Nvidia’s latest Blackwell AI chip racks are facing overheating issues, prompting major customers to delay or reduce their orders. Early shipments have reportedly suffered from technical glitches, affecting how the chips connect within data centre racks. As a result, companies including Microsoft, Amazon, Google, and Meta have scaled back their purchases, some opting for older Nvidia AI chips instead.
The hyperscalers had initially placed orders worth at least $10 billion each but are now reconsidering their plans. Microsoft, for example, intended to install 50,000 Blackwell chips in a Phoenix facility but has since switched to Nvidia’s previous-generation Hopper chips at OpenAI’s request. Nvidia has not commented on the situation, while Microsoft, Google, and Meta have yet to respond to inquiries.
Concerns over Nvidia’s sales extend beyond the overheating issues, as the US government has announced tighter restrictions on AI chip exports, potentially impacting revenue. Despite the setbacks, CEO Jensen Huang remains optimistic, stating that the company is still on track to generate billions in revenue from Blackwell chips this quarter. Huang has also denied earlier reports of overheating in liquid-cooled Blackwell servers.
