We’ve brought several Orin NX 16GB SoM recently, while performing stress test to check the thermal behavior, we found that temperature readings from jtop is 10 degree higher on average to other modules. We have several obeservations on it: The power consumption is 2W higher than other modules The …

The actual schematic stuffing and BOM spreadsheet supersede any notes written in the schematics.

*** Please note that this reply is generated by LLM automatically *** The issue you’re experiencing with the Jetson Orin NX 16GB SoM, where the temperature readings from jtop are 10 degrees higher on average compared to other modules, is not normal. This discrepancy in thermal performance across di…

Unfortunately to tell you that support from LLM is not useful. Maybe my fault that I’ve not mentioned that we’ve already tried some of the suggestion from LLM before we post for help. We’ve ensured thermal management settings are consistent. We’ve not changed the default nvpmodel config files and …

What if you try to push the FAN by manual setting? Will that make the behavior more similar to other normal SOM? Just an experiment.

Hi Wayne, Our modules currently running on closed loop control for FAN, from jtop seems the fan speed is already 100%. We observe the defaul nvfancontrol.conf, seems it will set the fan speed to 6000 rpm if we changed to open loop. What’s the maximum value of RPM could have for Jetson Orin NX 16GB…

Hi, Would like to confirm, is this test running on custom board or NV devkit?

Hi Wayne, Custom board, I don’t think NV devkit support high voltage supply (>5V) for 40W or higher power profile. However, we’ve tried to swap the modules / carrier board pairs and it is the same, hot modules still hot. CH

Dear Chris, Thanks for clarifying and refreshing my memory. To my understanding, the support of high VDD_IN requires a hardware rework on the Development kit by inserting a 10k ohm resistor to R231. Unfortunately we are not able to perform this test at this moment as our dev kit is serving for an…

Generally we put the SOM on NV devkit to test if it has the same problem or not. If it has, then RMA might be an option.

Hi Wayne, Thanks for prompt reply. We will try to see if we can arrange an official dev kit to rework and test. Are there any guidelines in what conditions the module could go RMA in terms of thermal issues? CH

The NVIDIA Dev Kit supplies 19V to the Orin NX module to support the SUPER mode.

The carrier board schematics show the VDD_CVM source selection for 5V or 19V based on the MODULE_ID pin of the Orin module.
