well i attempted to do the fan mod yesterday by using voodoobox method and was unsuccessful. i followed it and from what i understand the wires that i was to tap into were not to be powered. well these had power. i thought i was to ground the circuit which would complete it. was this wrong??? does anyone know where i can get an online diagram of the wiring for the fans. it does not have to be 56k friendly as i have DSL. i jsut need to look it over and see if i can do something of my own.
