Script to control nvidia GPU fan speed in Linux.

(No GUI Required,just need SSH)(Perhaps the simplest)

Fan curve points Graph

Quick Start

Set up Environment

python3 -m venv fan

Activate Environment

source fan/bin/activate

Install pynvml

pip3 install pynvml

Get python file

wget https://raw.githubusercontent.com/RoversX/nvidia_fan_control_linux/main/nvidia_fan_control.py

Return to the previous directory maybe

cd ``

Create fan.sh for simple use

nano fan.sh

Copy script into the file

#!/bin/bash

# Use sudo to elevate privileges and activate the virtual environment
sudo bash <<EOF
source /home/x/Workspace/fan/bin/activate
python /home/x/Workspace/fan/nvidia_fan_control.py
deactivate
EOF

Start fan control

./fan.sh

Version 1

Enhanced Points

A more user-friendly UI has been added to the original version to facilitate user adjustment.

Example Output

x@x:~$ ./fan.sh
[sudo] password for x: 
============================================================

If you want to draw fan speed curve

import matplotlib.pyplot as plt

# Fan Curve Parameters
temperature_points = [0, 40, 57, 70]
fan_speed_points = [30, 40, 80, 100]

# Draw curve
plt.figure(figsize=(8, 6))
plt.plot(temperature_points, fan_speed_points, marker='o', linestyle='-', color='b', markersize=8)
plt.title('Fan Speed Curve')
plt.xlabel('Temperature (°C)')
plt.ylabel('Fan Speed (%)')
plt.grid(True)
plt.xticks(temperature_points)
plt.yticks(fan_speed_points)
plt.tight_layout()
plt.show()
