In a data center that cools servers using an airflow from a central fan, rather than individual server fans, the cooling needs for each server are met by creating a sufficient pressure differential across each server. Because the pressure differential is the same for all of the servers, it is desirable to operate the data center such that each server needs the same pressure differential for proper cooling. Accordingly, a load balancer assigns tasks to the servers based on the known cooling needs of each server in order to balance the pressure differential needed to cool the server. This information may also be sent to the central fan to ensure that a sufficient pressure is created by the fan. Determining the cooling needs beforehand avoids spikes in server temperature, thereby enabling the servers to operate safely at a temperature closer to their maximum rated temperatures.
