The question is really about the correct use of a transistor in this, or a similar situation. Specific values surely change from circuit to circuit, but I imagine the general concept remains the same; like for a lighting dimmer switch, for example. So, correct me if I'm wrong, but this is really just one of many examples I could have chosen, to give some context for the question. | |

But for arguments sake, I was working with a hypothetical value for the fans: 12V 100mA. As for the transistor, I don't have/know the specific model; its just a generic, default transistor used by the software (EveryCircuit). | |
