Hi,

I am working with a Jetson Orin NX (Super SSD version) and have developed a custom streaming pipeline that will be shipped to a client. During long-duration runtime, the device consistently restarts around midnight.

After investigating the logs, I found repeated “hot surface” thermal errors, followed by an automatic restart. I also observed that:

  • The CPU, SSD, and fan area become extremely hot

  • The fan is running, but cooling seems insufficient

  • I tried switching the fan mode from quiet to cool, but the temperature is still very high

  • This test was performed in a cool environment, but the final product will be:

    • Deployed in a hot environment

    • Installed inside an enclosure, which will further increase temperature

Because of this, I am concerned about long-term stability and safety.

I would appreciate guidance on the following:

  1. Thermal Management & Monitoring

    • Recommended methods to track thermal behavior (CPU, GPU, SSD, surface temperature)

    • How to identify which component is triggering the hot surface error

  2. Power & Performance Configuration

    • Best practices for configuring to reduce CPU/GPU power consumption

    • Recommended power modes for continuous streaming workloads

    • Any Jetson-specific configurations to limit thermal throttling or peak power

  3. Cooling & Hardware Recommendations

    • Suggested heatsinks for Jetson Orin NX and SSD

    • Recommended thermal pads / thermal paste

    • Whether an SSD heatsink is required for the Super SSD version and suggested product

    • Fan recommendations or fan curve tuning options

  4. Deployment Considerations

    • Best practices for enclosure design (airflow, vents, active cooling)

    • Any NVIDIA-recommended thermal design guides for Orin NX

Any working configurations, documentation, or real-world recommendations would be extremely helpful.
