Hello,
I have an NVIDIA Jetson Orin NX 16GB device that is used for testing and development. During use, the device’s CPU reached its thermal slowdown temperature of 99 degrees Celsius, which lead to myself powering it down since the temperature was high, current intake dropped by about half, and CPU core frequencies dropped from 1500 MHz to about 1000 MHz. After it was powered down and rebooted shortly after, the temperature was shown to be at about 75 degrees Celsius, the current intake remained low, and the CPU core frequencies operating at a constant 115 MHz. This is peculiar because the temperature did not go higher than 75 degrees Celsius, Current intake was low, and the CPU core frequencies operating at a constant frequency.
Could this be due to any hardware governors that activate and place a protocol when the device is rebooted after reaching it’s slowdown temperature, and still being fairly hot once rebooted? Otherwise, could it something else that may be causing this anomaly?
It can be seen here in the photo that I’ve attached from the device that it has a scaling governor, frequencies, and etc. I am unsure if possibly the hardware governor is having an effect?
Notably, the device did not have a heatsink nor active fan on the system on chip, as I do not use it for personal operating purposes an do know that a higher temperature can be reached without the use of a heatsink. However, I am merely curious as to why this anomaly occurred after reboot, as it should have returned to normal once it was cooled off?
Thank you for you assistance with this matter and knowledge that may be presented on this matter to address this issue.
