We discuss the cavity cooling dynamics which accompanies synchronization of dipoles in a resonator. The atomic transitions are incoherently driven by an external pump and strongly coupled to a cavity. Friction forces and diffusion depend critically on the external parameters, and can lead to recoil temperatures in the synchronization regime. By means of a mean-field analysis we show that this is accompanied by an onset of correlations between internal and external degrees of freedom and determine the phase diagram for the stationary state as a function of the external pump strength and of the superradiant linewidth.
