Linux GPU Fan Control: A Step-by-Step Guide to Optimizing Your Graphics Card

When it comes to high-performance computing applications, maintaining optimal temperatures is crucial for prolonging the life of your hardware. Linux offers a range of tools and configurations that allow you to fine-tune your graphics card's fan control settings, ensuring maximum performance while keeping noise levels to a minimum.

In this article, we'll explore the process of setting up and configuring Linux GPU fan control using NVIDIA GPUs. Our guide covers Ubuntu 16.04.2 LTS and CentOS 7.4 with CUDA 9.1, making it compatible with various NVIDA FE GPU cards and some Zotac cards.

The first step is to enable all GPUs using the `sudo nvidia-xconfig` command with specific options. The key here is to set the `cool-bits=7` option in the `/etc/X11/nf` file, which allows you to control fan speeds. Without this setting, attempting to adjust fan speeds will be ineffective.

To create a new configuration file or check existing settings, run the following command:

sudo nvidia-xconfig -enable-all-gpus -allow-empty-initial-configuration -cool-bits=7

Next, ensure that Xorg is installed and configured correctly. This might involve installing Xorg and creating a new configuration file using the command above.

The good news is that our guide has been tested on multiple platforms, including Ubuntu 16.04.2 LTS with EVGA GTX 1050 Ti GPUs, Ubuntu 16.04.3 LTS with EVGA and ASUS GTX 10 Ti GPUs, and CentOS 7.4 with CUDA 9.1.

To make these settings permanent and without requiring a display attached (a headless system), follow these steps:

1. Install Xorg and create the necessary configuration file.

2. Run the `sudo nvidia-xconfig` command with the specified options to enable all GPUs and set fan speed control.

3. Configure your system to start the Xorg server on boot.

In datacenter and remote server environments, it's common to run a headless system without a desktop environment. To achieve this, you'll need to install Ubuntu Server without a desktop environment and ensure that you have a command prompt available after reboot.

By following these steps, you can optimize your Linux GPU fan control settings for maximum performance while keeping noise levels in check. This is particularly important for high-performance computing applications where maintaining optimal temperatures is crucial for prolonging the life of your hardware.

With this guide, you'll be able to fine-tune your NVIDIA GPU's fan speed profiles and keep your system running smoothly, even in datacenter environments.
