Fan Curve Manager

Notes

The funcionality of this package was introduce in LenovoLegionLinux with this PR so this package is not needed if you are using LLL python gui and cli

Overview

Small script that will apply a given profile.
Needs kernel module to work.
It'll read a give profile with sudo python profile_man.py -i $PROFILE, back up your default config for that mode and change it.

Features

Non permanent, by design.
Daemon to chage automatically to the profiles in /etc/lenovo-fan-control/profiles, with updating on mode change and battery events
Folder location and fancurve files name can be change by editing /etc/lenovo-fan-control/fancurve.sh
Expandable and scriptable, with tiny adjustments you can load easily, such as backing up all profile modes or tweaking to only parse.
Supports custom profiles on the following format:

#PROP NAME (acc/decelaration,fan1/2rpm,gpu/cpu/ic max/min temp)
1 #value for point 1,...
2 
3 
4 
5 
6
7 
8 
9
0 #last point is performance mode only, so value only matters in that mode

should be compatible with all models of the kernel module
janky, as such, please sanitize your input
Gpu TDP change for AMD and NVIDIA (an be change by editing /etc/lenovo-fan-control/fancurve.sh)
Can change the Minicurve option
ADD CPU control (Intel and AMD) need to see the repo fro RyzenADJ or undervolt on how to configure via cli and edit the CPU_CONTROL_COMMAD variable in the file /etc/lenovo-fan-control/fancurve.sh
Now uses legion_cli from LenovoLegionLinux project

Install Systemd Service (optional)

Note: acpid daemon is needed to systemd service restart when plugged into AC and the charger is removed.

Change the fan curve files on the repo to your liking and run the install.sh script (DONT RUN WITH SUDO) Attention: the presence of zero in the balanced and quiet files is because the queit and balance modes only have 9 and 8 fan point respectively, please add zero until they have 10 lines

Location of the fan curves after install: /etc/lenovo-fan-control/

Notes:

When using this service you need to disable, if you want to, the default behaviour using this command: sudo systemctl disable --now lenovo-fancurve.service lenovo-fancurve-restart.path lenovo-fancurve-restart.service
Dont use quiet mode on long intensive tasks on both battery and charger.

Gpu TDP change

WARNING:ONLY WORKS ON 525 NVIDIA DRIVER; AMD WORKS ON ANY VERSION TO MY KNOWLEDGE

WARNING:I DON'T HAVE AN AMD MACHINE, SO PLEASE OPEN AN ISSUE AND REPORT IF IT WORKS

Setup

The TDP change is made using the nvidia-smi for NVIDIA GPUs and rocm-smi for AMD GPUs (CPU control will be added in the future). To enable this feature, edit or create the follwing file

/etc/lenovo-fan-control/.env
#!/bin/bash

# Remove the comment for your configuration

#RYZEN (Cpu TDP control using RyzenADJ)
#INTEL (Cpu TDP control using undervolt) [https://github.com/georgewhewell/undervolt]
#Disable by default see the github from both project
#CPU_Control = 0
#NVIDIA (nvidia-smi)
#TEAM_GREEN=1
#AMD (rocm-smi)
#TEAM_RED=1

NVIDIA Notes only: Try to change the nvidia gpu TDP with this command: nvidia-smi -pl 140 If doesn't work run this command and retrying (this command break supergfx funcionality):

systemctl enable --now nvidia-persistenced.service

Both nvidia and AMD:

If /bin/nvidia-smi (for nvidia user) or /bin/rocm-smi (for amd users) doesn't exist, create this sym link:

# For Nvidia
ln -P /opt/bin/nvidia-smi /bin/nvidia-smi
# For AMD
ln -P /opt/rocm/bin/rocm-smi /bin/rocm-smi

For supergfx users I recommend creating this alias on .bashrc or .zshrc:

alias hybrid_mod="supergfxctl -m hybrid && systemctl start nvidia-persistenced.service"
alias integrated_mode="systemctl stop nvidia-persistenced.service && supergfxctl -m integrated"

Changing Values Please get the values of the Base TDP amd MAX TDP for your graphics card: With these two values you can change a few lines in the file /etc/lenovo-fan-control/fancurve.sh

This is a exemple of you can set (3070 values):

For quiet you set the base tdp or lower (GPU_TDP=80)
For perfomance you set the MAX tdp (GPU_TDP=115 [you can set to 125 if you have a clevo vbios])
For balance you can set the base tdp if you set lower in quiet (GPU_TDP=130 [you can set to 140 if you have a clevo vbios])

Obligatory don't take me to court

no warranty, your risk, my project, linux only (why are you here then)

Thanks to the legion fan module

Thanks for the systemd service

Note:

This package and dependency will be updated to the aur for now when using PKGBUILD comment out the dependency and install the module before hand
