The Steady-State GPU Temperature on the Jetson AGX Orin is Higher Than in Previous Tests

Hi,

I am developing an industrial PC using the Jetson AGX Orin, and I am evaluating its cooling performance by applying a high load to the CPU and GPU.

The issue is that the GPU temperature is 8°C higher on July 5th compared to the test conducted on April 26th.

My questions are:

  1. The GPU temperature increased to 95.0°C from 86.7°C despite the same test conditions. Is this temperature of 95°C the actual temperature of the GPU, or could it be a measurement error from the GPU temperature sensor?
  2. If the GPU temperature of 95°C is indeed the correct and real temperature, why did the GPU temperature increase by 8.3°C (from 86.7°C to 95.0°C) under the same conditions?

This is the board to be installed in the PC.We are currently testing the board independently.

Hi,
For information, do you use different Jetpack releases and observe the issue? Or the Jetpack version is not changed?

Thank you for your reply!
I didn’t change the Jetpack version during this period.
I’m currently using version r35.4.1. Should I try different versions as well?

Hi,
We would suggest re-flash Jetpack 5.1.2(r35.4.1) and see if the issue is still present. Also can try 5.1.3(r35.5.0) and 6.0GA(r36.3).

OK, I will try it.
Is the purpose to determine whether it is a hardware issue or a software issue?

Hi,
Thank you for your support.
I tested both reinstalling Jetpack 5.1.2(r35.4.1) and Jetpack 6.0GA(r36.3), but in both cases, the issue still occurred.

Have you heard of similar issues? I searched the Developer Forum but couldn’t find any similar issues.

Hi,
We don’t see similar issue before. If you flash the same Jetpack 5.1.2 and GPU goes to 95C instead of 86.7C, it seems to be something different in hardware. Probably the thermal paste dries out.

Yes I did, and currently my AGX goes GPU thermal throttling in same condition.

Do you have any idea why only the GPU temperature increases?
Could this situation occur if some part of thermal paste is getting worse?
