An icemaker assembly for a refrigerator includes a support bracket having at least one support arm and a rear panel section, a bin slidably attached to the at least one support arm, an icemaker unit having an ice mold is also supported by the at least one support arm within the freezer compartment. The icemaker assembly also includes a fan mounted to the rear panel portion of the support bracket. The fan is selectively operable to direct an airflow onto the icemaker unit in order to speed ice production. Operation of the fan is tied to activation of a water inlet valve. A controller is coupled to the fan and the water inlet valve such that once the water inlet valve opens, fresh water enters the ice mold and the control activates the fan to hasten the production of ice.
