In one aspect, a non-transitory computer readable media has instructions encoded therein which, when executed by a computer processing system, cause the computer processing system to perform a method comprising receiving information indicative of coolers and information technology (IT) racks in an IT room, displaying a representation of the coolers and IT racks in a graphical user interface (GUI) of a computer system, performing a computational fluid dynamics (CFD) analysis to calculate results including airflow patterns, temperatures, and pressures in the IT room, determining, based on the CFD results, a load on each cooler in the IT room, and for each of the coolers in the IT room, displaying a graphical indication for the representation of each respective cooler of whether a Cooling Efficiency metric for that cooler is in a first or a second state based on the load on that cooler.
