The nvidia-fan-control utility is a user-friendly tool designed for controlling the fan speed on NVIDIA GPUs. It seamlessly integrates with Wayland display servers, making it an ideal choice for modern Linux environments.
- Automatic Fan Curve: The utility implements a pre-configured fan curve that intelligently adjusts fan speeds according to GPU temperature, ensuring optimal cooling without any user intervention.
- Easy Execution: Run the utility with a simple command:
sudo ./Rust-gpu-fan-control. - Autostart Capabilities: Can be configured to automatically start with your Linux distribution, providing hassle-free operation from boot.
- Proprietary Driver Support: Tailored for the NVIDIA proprietary driver.
- Open Source Driver: Compatibility with the open-source
nouveaudriver has not been tested but could potentially work.
- Monitoring support for amdgpu: Tested on (RDNA3/RDNA2/Polaris 30)
To start the automatic fan control:
chmod +x Rust-gpu-fan-control # used for allowing execution permissions
sudo ./Rust-gpu-fan-controlIf you need help with flags just type sudo ./Rust-gpu-fan-control --help
For the Bash version, use these commands:
wget 'https://github.com/UnknownSuperficialNight/nvidia-fan-control/raw/main/Bash_version/nvidia-fan-ctrl.sh'
chmod +x nvidia-fan-ctrl.sh # used for allowing execution permissions
sudo ./nvidia-fan-ctrl.shFor compiling the Rust version, execute these commands:
git clone https://github.com/UnknownSuperficialNight/nvidia-fan-control.git
cd nvidia-fan-control
cargo build --release
sudo ./target/release/nvidia-rustRust binary's in the releases are optimized for minimal binary size, while also being optimized for speed.
Clone the repo:
git clone https://github.com/UnknownSuperficialNight/nvidia-fan-control.git
cd nvidia-fan-controlEdit ./src/main.rs inside find a variable you would like to change options below:
REFRESH_TIME is how responsive the terminal is to resizing and the speed at which it will update the tui:
FAN_AMOUNT is the amount of fans on your gpu you wish to target
GPU_NUMBER is the target nvidia gpu if you have one gpu its typically 0
Use this command below to list gpus
lspci | grep -i vgaThe line at the top is 0 each line down is then incremented by one so if your gpu is on line 2 then its 1 since we count from 0 up
SPEED array is the most difficult to explain but here is a TLDR:
It finds the nearest number to your current gpu temp and selects the fan speed to run at that speed
Example:
[25 50 75 100]: In this case if your gpu temp is 63 the closest number in the array is 50 thus the speed is 50% until it passes over the threshold of 65 since 66 is closer to 75 than 50 it changes the gpu speed to 75%.
The speed array in both versions is used to customize the speed. It will by default find the closest value relative to the current temperature. So, if the lowest value in the array is 59°C and your current temp is 30°C, then 59% speed will be selected. However, if in the array you have the current temp of 30°C and in the speed array you have these values [26, 35, 59, 80], then in this case, it will choose 26 as it's closest to the current temp.
Thus, change the array how you see fit to make it work for you. I've set it up to work for my GPU as mine can only be at 59 speed at minimum.
Also, you can change the code. Currently, I have it set so that if the temp is incremented from 70°C to 85°C, thus making the fan speed 100% at 85°C. It also ensures the fan speed does not go over 100%.
Thus, if you want to remove or change it, going to 100% once it hits 85°C, then the code is at this Line
