    looking for a control unit on sale here, something like a digidoc but that will work with 12v and 4 pin. they sell them at www.overclockingstore.co.uk, call them bay bus but i dont really want the hassel of ordering from england.

    Goto the Hardware Tweaking board.

    I'm working on a home made thing that would be very cheap. Can be easily adapted too.

    The baybus is handy if you want something with a logo, warranty and a LCD temp readout. It has some nice features too, but the POTS (afaik) wil burn out eventually anyways.

    The method I'm working on involves a voltage splitter so, hopefully, it won't generate heat and hence won't burn our. I hope. Involves divverent Ohm Resistors, bits of wire and a 2 or 3-way switch. Might want something to mount it on too.

    I'll have a few diagrams of soemthing up soon enough.

    your thinking of the digidoc, the baybus is a straight forward on off type thing.

    Syxpak, if you use resistors, you will generate heat. To avoid this, you will need to use switching voltage regulators, which still generate heat, but not nearly as much since they are so much more efficient.

    I use variable resistors in my own machine, in fact they of the type that are used as volume controls in radios, they can handle a lot more power than your normal rheostat, since they are made quite differently. I am well familiar with burning out variable resistors, but these ones have been in my machine for a year or more, in use almost 24/7, and are still working fine.
