Apparatus and method are provided for two-phase dielectric cooling of an electronic device. The apparatus includes a coolant flow path, a vapor condenser and one or more vapor fans. The coolant flow path is in fluid communication with the electronic device, where liquid dielectric coolant within the flow path vaporizes upon contacting the electronic device, forming dielectric coolant vapor, and thereby facilitating cooling of the electronic device. The vapor condenser is also in fluid communication with the coolant flow path and facilitates condensate formation from the dielectric coolant vapor. The one or more vapor fans are disposed within the flow path to actively move dielectric coolant vapor into contact with the vapor condenser, and thereby enhance cooling of the electronic device by facilitating coolant condensate formation and thus recirculation of the coolant condensate as liquid dielectric coolant.
