in the next couple of weeks I'm going to build a variac fan controller at the moment I have two fans intake and exhaust my exhaust fan has already got two speeds by connecting the live wire to another terminal block can I still use this fan with the variac transformer.
Inside the fan there is a black box I would imagine it's some kind of resistor there is a couple of wires coming out can I disconnect it somehow because I don't want to buy new fan.
Thanks.
