[Solved]Asus laptop temperature going to 60°C on AC but not on battery

Hello !
I am looking for why my laptop temperature grow up to 60°C on AC but not on battery.
When I start my laptop plugged on AC, my laptop quickly goes to 60°C when it stabilizes (My fans starts at 45°C or 50°C and accelerate at 60°C).

When I unplug my laptop from AC, the fans accelerate to reach a temperature of 55°C when they decelerate. Then, the temperature drops to 35°C when the fans completely stop. While I am on battery using apps that do not need high cpu/gpu consumption, the temperature does not reach a too high level of temperature. If I plug again my laptop to AC, the temperature keeps going down to 35°C without going up again for a moment (Maybe, when I start to request more and more cpu/gpu usage ?)

I am using laptop-mode to reduce power consumption so I tried to activate it even if my laptop is plugged to AC but it does not change anything.
To avoid potential conflicts with an other problem that I have with my GPU, I deactivated my discrete GPU modules (nvidia, nvidia_drm and nvidia_modeset by using "install <module> /bin/false" in a file in "/etc/modprobe.d". Neither these modules, neither nouveau module shows on lsmod)

I suspect something listening to ACPI event 'AC unplugged/plugged' to reduce consumption of something else but I did not find what could do that.

Any ideas about this problem ?

Hey hey hey !
I finally managed to solve my problem ! I was wanting to make my HDMI port working and the solution I found to this problem solved my laptop overheating problem at the same time ! Here is what I did :
- I added nvidia-drm.modeset=1 to my kernel parameters.
I hope this could help someone else.
