A baffle facilitates the flow of air from a first side of a data center rack into an intake on the opposite side of the data center rack. The baffle may be configured to couple to the bottom side of the rack. The rack itself may be located in a data center with at least one cold aisle and at least one hot aisle, such that cold air from the cold aisle may flow through the baffle and into an air intake of the rack facing the hot aisle. The baffle may additionally include fans to pull air into and through the baffle, and may include an air conditioning unit or a chiller system to cool air flowing through the baffle.
