High Idle Temperature with Industrial Module Compared to Developer Kit

[eteo4771]

Hello,

I’m currently working with both the Jetson AGX Orin Developer Kit (64GB Commercial module + Carrier Board) and a separate 64GB Industrial module.

When using the Developer Kit in 30W mode without a fan, the idle temperature stayed around 50°C. I recently tried running the Industrial 64GB module on the same DevKit Carrier Board in 35W mode, also without a fan, and noticed that the idle temperature hovers around 61°C.

I expected similar thermal behavior since I’ve attached a heatsink to the Industrial module, and I wasn’t using a fan in either case. However, The Industrial module seems to run at a higher temperature.

Is this kind of temperature difference expected for the Industrial module? Any suggestions on how to bring the idle temperature of the Industrial module closer to the Developer Kit’s?

AGX Orin Industrial 64GB module + DevKit Carrier Board

$ sudo nvpmodel -q
NV Power Mode: 35W

$ cat /sys/class/thermal/thermal_zone8/temp

AGX Orin 64GB Developer Kit

$ sudo nvpmodel -q
NV Power Mode: MODE_30W

$ cat /sys/class/thermal/thermal_zone8/temp
50250

Thanks.

Can you run the test in the same W to compare?

I set both modules at 15W power mode, and the temperature difference is similar to what I saw before.

Hi,

As the SOM is not fully same, I don’t think comparing this makes much sense here.

Also, the power mode means the upper limit to the power you could run at that stage, not means it will be same mode.
