    Hardware

    gpu-fans-find — spin GPU fans from the first card to the last to make it easier to find the required GPU. You can specify the card number, then the fans will start on it. If the worker starts up correctly, it's quite easy to track which card corresponds to which bus. For example, if the GPU0 card has a 01:00.0 bus and you want to find it, use the command gpu-fans-find 0. This command will spin up the fans only on this card for a while. And so on, following the example.
