Provided is a support assembly for a pagewidth printhead module having modular printhead integrated circuits. The assembly includes a support frame and a plurality of PCB supports operatively supported by said frame, with each support defining busbar channels for locating busbars to supply the integrated circuits with power, and each PCB support operatively supporting a PCB with a print engine controller for controlling respective integrated circuits. The assembly also includes a cover portion configured to engage said frame to enclose the PCB supports. The cover portion has heat coupling material for thermally coupling with the respective print engine controllers when engaging the frame to facilitate heat dissipation from the controllers.
