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.

This was a great advice. Thanks

My rig is working great.
4xVega46 @28.Mh/s on stock settings except the fan speed.
Unfortunetly stock setings becouse I cannot OC.
Tried to use rocm-smi. No luck.
GPU[2] : Supported GPU clock frequencies on GPU2
GPU[2] : 0: 852Mhz
GPU[2] : 1: 991Mhz
GPU[2] : 2: 1084Mhz
GPU[2] : 3: 1138Mhz
GPU[2] : 4: 1200Mhz
GPU[2] : 5: 1401Mhz
GPU[2] : 6: 1536Mhz *
GPU[2] : 7: 1711Mhz
/opt/rocm/bin/rocm-smi --setsclk 7
But that does not change anything.
Since those cards will be water cooled I wondering how to OC?
The only way is to flash my Vegas with LC bios? Really?
Cheers.
