You have to design your hardware to tolerate being run in consistently hotter conditions. There's a tradeoff between cooling cost and failure rate / capex.

Doesn't look like they made the hardware more tolerant of temperature, rather they made it remove waste heat more quickly.

"NVIDIA’s thermal engineering team reworked how those components handle heat, designing cooling loops that simplify how liquid is routed to multiple high-power chips on the board using a single inlet and outlet, resulting in a cleaner tray-level cooling architecture"

Nvidia's automotive and aerospace variants get ratings up to 85C, for comparison.
