Possible thermal throttling?
I have read is not the thermal pads… but a bios issue to be flashed into the cards (at your own risk!)

If you want to read the story… and from there there is another reddit link.
I had issues for weeks and was driving me up the wall. I finally opened a remote she’ll to my rig. You type in I think driver_uodate. It auto updates nividia drivers. I then was able to get my 93mh up to 98 and my 96mh to 99. Def made a big difference and noone tells you this. It is different than updating each card I guess. Def made a world of difference now two hours no shutdown…I am confident I can get to 100 plus but want to see if it runs all night. I’m at 1060 2100 and 230. Hope this helps you as I was constantly doing restarts or down at 93 mh on some. I run 6 rtx 3080.
my power cons is 245w my hash is 99/101
Thought some 3080s were power limited in the firmware. Remember reading some worked better after reflashing with a different firmware. Not sure if this is the cause for this.
If you you think it is thermal throttling you can try this command to see the reason
nvidia-info | grep Throttle
