A data processing unit includes a chassis configured to contain a line card. The chassis defines, at least in part, a portion of a first flow pathway and a portion of a second flow pathway. The chassis is configured such that a first portion of a gas can flow within the first flow pathway between an intake region and the first end portion of the line card such that the first portion of the gas flows across a first end portion of the line card in a first direction. The chassis is configured such that a second portion of the gas can flow within the second flow pathway between the intake region and a second end portion of the line card such that the second portion of the gas flows across the second end portion of the line card in a second direction opposite the first direction.
