An information handling center includes an information handling system (IHS) rack configured to receive cooled fluid from a pressurized plenum. The IHS rack includes at least one ventilator that is operable to cause cooled fluid to be drawn from the pressurized plenum into the IHS rack. A cooling fluid supply unit is coupled to the pressurized plenum and operable to cool a fluid passing through the cooling fluid supply unit and direct that cooled fluid into the pressurized plenum. A fluid flow control is located in the cooling fluid supply unit and coupled to a pressure sensor that is operable to determine a pressure in the pressurized plenum. The fluid flow control is operable to adjust the flow rate of the fluid passing through the cooling fluid supply unit based on the pressure determined by the pressure sensor. In response to the pressure sensor determining a pressure change in the pressurized plenum, the fluid flow control adjusts the flow rate of the fluid passing through the cooling fluid supply unit to adjust the pressure in the pressurized plenum.
