Are you able to check the bios to see if there is a fan speed profile in it? Maybe the reset cleared the fan profiles (or turned them off entirely).

I'm not sure how GPU fans work on the laptop, but I'd assume there is some sort of cooling with them too. So it's also worth checking the Nvidia drivers to see whether there is a fan speed setting for the RTX3050 as well.
And finally, I assume you've updated your various drivers to the latest versions?
