Hot processor in the laptop. My notes

The problem with laptop heating has been haunting me for a very long time.
This problem is especially present in powerful laptops.
I will leave valuable information here, for myself and for you.
Let's start!

So, we have a laptop MSI GV72 7RE
Intel i7 processor: Skylake i7- 7700HQ 2.80-3.80GHz
Integrated graphics: Nvidia GeForce GTX 1050 Ti Mobile

The initial temperature of the processor, with the default installation of BunsenLabs (Debian10), was 51-53°C

1. The first thing I did was install the drivers on a discrete Nvidia video card
For Debian Buster I only found bumblebee installation, here is the link (https://www.pcsuggest.com/install-and-c … -in-debian), or you can use the Debian wiki bumblebee
After installing the driver on my MSI laptop, to boot the system, you need to write the following to the Grub bootloader:

acpi_osi=! acpi_osi="Windows 2009"

You may not need this for your laptop, BUT you may need to change the entry to:

acpi_osi=! acpi_osi="Windows 2012"

or

acpi_osi=! acpi_osi="Windows 2015"

or

nomodeset nouveau.modeset=0 radeon.modese=0 i915.modeset=1

After installing the video card driver, the temperature dropped to 47-49°C

2. The second thing I did was install tlp

sudo apt install tlp

But the standard tlp settings did not help me, I need to fix the configuration file.
In the /etc/tlp.conf file, change

RUNTIME_PM_DRIVER_BLACKLIST="nouveau nvidia" 
RUNTIME_PM_ON_AC=auto
CPU_BOOST_ON_AC=1

Tlp settings lowered CPU temperature to 43-45

There are some more recommendations on the internet such as:

echo "1" | sudo tee /sys/devices/system/cpu/intel_pstate/no_turbo

or

sudo nano /etc/default/grub 
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=disable"
and
sudo update-grub

Disabling intel_pstate through the boot loader lowers the processor boost when needed, this can result in lower temperatures ... but problems may arise in the future

3. the third thing i did was install throttled github(https://github.com/erpalma/throttled)
I installed according to the instructions

sudo apt install git build-essential python3-dev libdbus-glib-1-dev libgirepository1.0-dev libcairo2-dev python3-venv python3-wheel
git clone https://github.com/erpalma/throttled.git
sudo ./throttled/install.sh
sudo systemctl enable --now lenovo_fix.service

ATTENTION!
If you put intel_pstate = disable in your bootloader Grub, Grub2, this script will not work or will not work correctly
Remove this line  intel_pstate=disable  from GRUB_CMDLINE_LINUX_DEFAULT ="quiet splash ..."

Next, set up the configuration file for your laptop or computer...
You can use the settings as (https://amanusk.medium.com/an-extensive … a7d853856c) or as (https://github.com/erpalma/throttled)

My settings in the /etc/lenovo_fix.conf file look like this:

[UNDERVOLT:BATTERY]
# CPU core voltage offset (mV)
CORE: -110
# Integrated GPU voltage offset (mV)
GPU: -90
# CPU cache voltage offset (mV)
CACHE: -110
# System Agent voltage offset (mV)
UNCORE: -90
# Analog I/O voltage offset (mV)
ANALOGIO: 0
.......
[UNDERVOLT.AC]
# CPU core voltage offset (mV)
CORE: -110
# Integrated GPU voltage offset (mV)
GPU: -90
# CPU cache voltage offset (mV)
CACHE: -110
# System Agent voltage offset (mV)
UNCORE: -90
# Analog I/O voltage offset (mV)
ANALOGIO: 0

After lowering the processor power supply, the temperature dropped to 37-43°C, in normal mode. I have not tested it at games

I hope someone will find this note useful.
If you have any questions about the text, ask... English is not my first language
Thank you for your attention
