Because tdxminer doesn't show info about temperature and fan speed, you can use utility of rocm drivers.

If you open new terminal beside your tdxminer and type:
/opt/rocm/bin/rocm-smi
you will get info about temperature, average power consumption, fan speed, and other info about your GPUs.
Problem with this command is that it only shows current state of your GPUs. If you want to monitor GPUs info for a certain interval, you can use watch command.

Type in your terminal:
watch -n 0,5 /opt/rocm/bin/rocm-smi
and you will get your GPUs info every 0.5 second.

I hope that this post will be helpful for some of you. Cheers.
