Abstract: A network-controllable cooling fan can have a recessed connector port with an internal tongue that defines an edge connector having a plurality of electrical contacts. The tongue can also define a plurality of electrically conductive tracks that electrically couple with the electrical contacts. Control logic can have a plurality of electrical connections and a logic bus that electrically couples the electrical connections of the control logic with the electrically conductive tracks defined by the tongue. An electrical biscuit-connector with internal electrical interconnections can join the network-controllable cooling fan with another network-controllable cooling fan, extending the logic bus while obscuring the electrical interconnections from a user's view.
