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.

- AlotOfReading 4mo agoNvidia's automotive and aerospace variants get ratings up to 85C, for comparison.
- taneq 4mo agoDon’t their consumer GPUs run at 85C core temp? Maybe not for as long though.
- NekkoDroid 4mo agoAMD CPUs basically all boost up to 90°C as a relatively normal operating temperature as long as the power (and some other factors) allow it to. I assume AMDs and NVs GPUs do to, but I play mostly CPU bound games so I see mine just sitting at ~60°C under load.
- frollogaston 4mo agoCore temp though. Ambient temp is a different story, and also depends on air vs water. In fact the article suggests the difference is getting the water more directly onto the chips, no mention of running at a higher core temp.
- AlotOfReading 4mo agoTemperature ratings are the allowed ambient temperature. The actual silicon will inevitably operate somewhat higher, because coolers are just moving heat down a temperature gradient.
- frollogaston 4mo agoDoesn'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"
