# AMDGPU Fan control service

Available commands:

* `service`        - Set fan speed depends on GPU temperature
* `set-automatic`  - Switch to GPU automatic fan speed control
* `set-manual`     - Switch to GPU manual fan speed control
* `available`      - Print available cards

#### amdfand set-automatic | set-manual [OPTIONS]

Optional arguments:

* -h, --help Help message
* -c, --card CARD GPU Card number

## Usage

```bash
cargo install amdfand

sudo amdfand monitor # print current temperature, current fan speed, min and max fan speed 
sudo amdfand service # check amdgpu temperature and adjust speed from config file 
```

## Config file

```toml
# /etc/amdfand/config.toml
log_level = "Error"
temp_input = "temp1_input"
update_rate = 4000 # time between checks in milliseconds
