Upon restart the fan of the desktop got loud again.
I cleaned the desktop from the dust but it was still loud (Lower than the first sound)
I tried to run nvidia-smi to see the temperature, couldnt see the driver
Tried to sudo apt update, didnt work
Tried to run sudo apt upgrade, worked
Ran sudo ubuntu-drivers devices
Then sudo ubuntu-drivers autoinstall
Didnt work
Then I just decided to remove all the nvidia drivers using
sudo apt-get remove --purge '^nvidia-.*'sudo reboot
After reboot the noise was gone.
So it seems after reboot some of the drivers were upgraded which were not compatible.
