A heat sink module for cooling a heat providing surface can include an inlet chamber and an outlet chamber formed within the heat sink module. The outlet chamber can have an open portion that can be enclosed by the heat providing surface when the heat sink module is installed on the heat providing surface. The heat sink module can include a dividing member disposed between the inlet chamber and the outlet chamber. The dividing member can include a first plurality of orifices extending from a top surface of the dividing member to a bottom surface of the dividing member. The first plurality of orifices can be configured to deliver a plurality of jet streams of coolant into the outlet chamber and against the heat providing surface when the heat sink module is installed on the heat providing surface and when pressurized coolant is provided to the inlet chamber.
