GPU Max Operating Temp seems low for Laptop 3060

Usually when looking at “nvidia-smi.exe -q -d TEMPERATURE” outputs, the GPU Max Operating Temp is within a few degrees of the GPU Slowdown Temp, however for the mobile 3060 (laptop) and possible other mobile cards, I’m noticing the GPU Max Operating Temp is quite low comparatively.

For my mobile 3060 the GPU Max Operating Temp is 87C while the GPU Slowdown Temp is 102C, that’s quite a significant difference and I can’t think of a scenario where it beings throttling at 87C and eventually hits 102C. As far as I know the GPU Max Operating Temp is when it starts to throttle clocks through SW and GPU Slowdown Temp is when it throttles via HW.

Anyone know why this GPU Max Operating Temp is so low, especially for a laptop GPU? I thought laptop GPUs were able to run hotter, and the high slowdown temp definitely indicates that. I’ve noticed alot of other desktop GPUs have max operating temps in the 90s.

Pasting my nvidia-smi query. Personally I think there’s an error and GPU Max Operating Temp for the laptop 3060 should be 100C, even the desktop 3060 has the GPU Max Operating Temp at 93C.

Hi there @raiger and welcome to the NVIDIA developer forums!

I am not the expert in thermal distribution theory, but the values seem correct to me.

You have to take into count that a Laptop form factor has completely different thermal constraints than a standard PC with an AIC GPU. Cooling systems differ from design to design and usually involve a holistic approach of cooling all components in an integrated cooling loop. That means CPU, RAM and other components temperatures will influence overall system values. That way if the GPU temp AND CPU temp for example spike, you can easily gain 10s of centigrade in a jiffy. That is why the (system) shutdown temp for the GPU is so high. But on the other hand, since heat dissipation is so difficult, the temperature where the GPU is clocked down will be much lower to safeguard against the whole system overheating too easily.

Again, this differs from manufacturer to manufacturer, but will be similar in any Laptop design. Besides, the GPU is a mobile version, so you can’t directly compare to desktop GPU values in any case.

I hope this clarifies things a bit.
