What kernel/OS/driver are you using if it is software I can try to 
reproduce since I have a pretty similar card.

In case it is is due to overheating this script will log temperature, 
power management and fan settings.

#!/bin/bash
cd /sys/class/drm/card0/device/hwmon/hwmon0
while `true`;
     do date;
     for x in fan1_enable fan1_input fan1_target pwm1 pwm1_enable 
temp1_input;
         do echo -n "$x: "; cat $x;
     done;
     echo; sleep 1;
done

Output will be the following about once a second:

Fri 28 Jan 2022 09:28:12 AM EST
fan1_enable: 0
fan1_input: 1714
fan1_target: 1714
pwm1: 0
pwm1_enable: 2
temp1_input: 36000

Also you can max out the fan to see if that helps:

echo 0 > /sys/class/drm/card0/device/hwmon/hwmon0/pwm1_enable

(If you can pwm1_enable after it will show 1 and not 0, but if you look 
at pwm1 it will be at max of 255).
