Update driver nvidea - trouble starting laptop or with the fan speed

Hi all,
I am new, with this forum and ubuntu. I received a laptop with ubuntu 20.04.1, and recently updated packages. I do not know why, but the fan “overheats” and makes some noise, even if I am only on internet. I’ve found that the solution was to update the graphic device. So what I did first was to copy paste in a terminal following lines:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
ubuntu-drivers devices
sudo apt install nvidia-driver-455

But the problem was still here. So what I did was to manually update the graphic device following this link (and tutorial) https://www.nvidia.fr/Download/Find.aspx?lang=fr&QNF=1

And it works. But, now I have another problem. When I start my computer, it freezes at the beginning with the screen “Dell Ubuntu”, and I have no other solution to press the on-off button… So again, I purged the nvidea driver and ran the first lines (with the install nvidia-driver-455), and still have the trouble with the fan.

What should I do?

details about my config:
Dell precision 3551
NVIDIA Corporation GP107GLM [Quadro P620] / Quadro P620/PCIe/SSE2
Intel® Core™ i7-10850H CPU @ 2.70GHz × 12
Ubuntu 20.04.1 LTS

I’ve the same issue, I received à laptop with a same config as you and updated it to ubuntu 20.04 in driver packages there’s many I’ve picked the 450 one. My fan alway is running and heat event no lot of programs running!

I’ve maybe found a “temporary” solution. I’ve installed the driver 455 (I do not know all the difference between them, but if I remember right this is about “propriety”, and 455 is “free”).

After restarting my computer, I’ve installed nvidea-settings and execute this program. You can have a look here, section 4.1 (https://doc.ubuntu-fr.org/nvidia, it’s in french but you can download the package and then run the command line). I went to the option “PRIME Profiles”, and changed “NVIDEA On-Demand” (by default it was selected "NVIDEA (Performance Mode). You should restart your computer after the change (it takes few minutes). I do not know if it is the best solution, but it works for me.
