NVIDIA Fan Control Guide

Overview

This project provides a dynamic fan control utility for NVIDIA GPUs using NVML. It includes:

• A custom fan curve based on GPU temperature.
• A systemd service for automatic startup and logging.
• A terminal-based GUI for configuring the fan curve interactively.

Steps to Set Up

1. Compile the C Code

First, locate the NVML header file:

find /usr -name "nvml.h"

Then, compile the program:

gcc -o nvidia_fan_controlV2 nvidia_fan_controlV2.c -I/usr/the/directory/that/includes/nvml.h/file/ -lnvidia-ml

2. Install the Systemd Service

Create a systemd service file:

echo "[Unit]
Description=NVIDIA Fan Control Service
After=multi-user.target

[Service]
Type=simple
ExecStart=/usr/local/bin/nvidia_fan_controlV2
Restart=always
User=root

[Install]
WantedBy=multi-user.target" | sudo tee /etc/systemd/system/nvidia-fan-controlV2.service

Enable and start the service:

sudo systemctl enable nvidia-fan-controlV2
sudo systemctl start nvidia-fan-controlV2

3. View Logs and Reconfigure

To view real-time logs:

journalctl -u nvidia-fan-controlV2 -f

TO BE IMPLEMENTED

To reconfigure the fan curve:

nvidia_fan_controlV2 --re-configure

Future Enhancements

(please contribute if you have any 2-Fan or 3-Fan architecture and you need a more complex fan_control design)

• Support for multi-fan GPUs.
• Improved adaptive fan curve options.
• A full-screen terminal-based GUI for configuring fan curves interactively.
