SSD heats up even when Rock 3A is power off

#1

Has anyone had a similar situation?
Is it possible to fix this with some software settings?

when you say power off, do you refer pressing the power button or via command line/GUI power off? The NVMe power is controlled by a GPIO.

Hello, Jack
Thank you for your help.

I understand correctly? That in order to remove power from external disks and other peripheral devices, it is necessary to close some one or several GPIO pins.

I have studied the information here
https://wiki.radxa.com/Rock3/hardware/rock3a-gpio

But it doesn’t say anything about power management. Tell me, is there a corresponding page where this is discussed in detail?

Do you have multimeter? Can you measure if the SSD power is still on 3.3V when the system is powered off?

Thanks for the detailed information. As it turned out, it’s not the SSD that gets hot. The CPU is heating up. In this case, heat is transferred through the board and metal racks, as well as through the connector and connecting cable to the SSD board. I will install a more powerful radiator.
