If your cabinets are only partially populated and have perforated ventilation holes in the front and rear, you may not need additional cooling fan kits. Server manufacturers typically recommend a minimum perforation factor for the doors of the cabinets that would be used to house their servers and this is typically from 63% upwards; to allow adequate air flow from front to rear.

Server Rack and Cabinet Height Conversion Table
The following table shows the height of a rack or cabinet in metric and imperial measurements. This is the internal ‘usuable’ height. The overall physical height will be larger dependent upon the type of rack or cabinet, its feet (which may be adjustable) or castors and cable entry points.
The table can also be used to calculate the total ‘U’ height of the equipment to be located in the rack or cabinet and how much space capacity is available for future expansion. For example total the height in millimetres (mm) and divide by 44.45 to get the approximate U height.
