A technique is described whereby air flow distribution throughout a computer system is controlled and dispersed, through the use of self- balancing baffles, based on the cooling requirements of installed circuit cards. Computing systems require the ability to install or remove operational features applicable to the customers' requirements. Circuit cards are added or removed, as required, to provide the flexibility to configure systems to many different configurations. This flexibility has caused an unbalance to the cooling system, when either fully populated or partially populated with circuit cards, assuming the same blower system is retained in all cases. The technique described herein provides a mechanism to automatically self-balance the air flow requirements to compensate for the variations in feature configurations.
