Disclosed are a system, method, and computer-readable medium for optimizing a fan control system inside a rack system. In at least one example embodiment, the system can include a rack server with a plurality of chassis each having at least one node, each of the nodes including at least one adjustable air vent and configured for adjusting the at least one adjustable air vent based on an air flow requirement of the node. The system can further include a plurality of fans, where the plurality of fans are configured to operate based on a control signal. The system also can comprise a fan control logic board, wherein the fan control logic board is configured to receive from each node in the plurality of chassis the air flow requirements and based on the plurality of air flow requirements generate and transmit the control signal to the plurality of fans.
