    The 12v circuit provided turn on by an open collector signal.
    Can somebody modify the circuit if I want to operate it with a toggle switch if the open collector signal pin is not activated?
    Please provide the circuit.

    Connect a single-pole, single-throw switch from the OPEN COLLECTOR input to GND.
    That way either the open collector signal or the switch can turn on the fans.

    I can't draw you a schematic, as I'm on a WebTV type thing and have no drawing tools availabie.

    sajelectric,

    I believe this is what SgtWookie is talking about.
