NVML is being used, because it is OS and display sever agnostic (that means it doesn't depend on X11 or Windows). Another important reason is that the official NVIDIA tool (NVIDIA smi) does not currently support fan control. + +## Disclaimer + +* This project is NOT endorsed or sponsored by NVIDIA +* This project is independent + +## Supported hardware + +* Any NVIDIA CUDA supported card with a driver higher or equal to version 520 + +## Dependencies + +To use it, you must have installed: + +* NVIDIA's proprietary drivers (>= v520) +* Python 3 +* [nvidia-ml-py](https://pypi.org/project/nvidia-ml-py/) (NVIDIA's official python bindings) + +You will also need **admin/root** privileges to be able to **set anything**. Query can be done by unprivileged users however. + +## Installation + +### Windows + +Install the package with [pip](https://packaging.python.org/en/latest/tutorials/installing-packages/) running as **admin** to make it system wide (needed for startup services) + +```bash +pip install caioh-nvml-gpu-control +``` + +### Linux + +Install the package with [pipx](https://github.com/pypa/pipx) running as root, so it can be [installed system-wide](https://pipx.pypa.io/stable/installation/#-global-argument) (needed for startup services). + +```bash +sudo pipx install --global caioh-nvml-gpu-control +``` + +> [!WARNING] +> Files must be writable only to admin/root, otherwise unprivileged programs may escalate provileges with the startup services.

(no admin or root) + +```bash +chnvml fan-control -n 'NVIDIA GeForce RTX 4080' -sp '10:35,20:50,30:50,35:100' --dry-run +``` + +* You can also revert to the original fan state by runnig the following command or *rebooting the machine* + +```bash +chnvml fan-policy --auto -n 'NVIDIA GeForce RTX 4080' +``` + +Note that it does not current support fan curve (or linear progression), so it works on levels. Each level the temperature is verified against the configuration (higher or equal) and then set properly. Also, each temperature associated with speed is ordered automatically. (think of it as a staircase graph) + +``` +Temp : speed(%) + +1. 40 : 100 (>=40°C - 100%) + +2. 30 : 50 (>=30°C - 50%) + +3. 20 : 30 (>=20°C - 30%) + +4.
