Nvidia-smi gives ERR! under Fan section when GPU temperature is low enough

https://forums.developer.nvidia.com/t/nvidia-smi-shows-err-on-both-fan-and-power-usage/68293/11 Talks about the same problem but the solution is to cool down the GPU.
I have tried every possible solution to that discussion but none of them works for me.
The problem sometimes got fixed after I shut down the computer for a while and rebooted, but sometimes not.
The problem sometimes got fixed after I take out the GPU and re-plugin, but, again, sometimes not.
Does anyone have any other possible solution?
I am using Ubuntu 20.04, GPU 3090. Let me know if I should provide more information.

If this is a (nearly) permanent problem that can’t be fixed by a simple reboot, the gpu might be damaged. You should try to have it replaced if still under warranty.
