Cooling System
The cooling system consists of separate subsystems (sets of fans and impellers) that draw room air into the chassis to keep its internal temperature below a maximum acceptable level. When the temperature is below the maximum, the fans and impellers function at less than full speed. If sensors detect that the temperature of a component has exceeded the acceptable maximum—for example, because an impeller is removed—the speed of the remaining impellers and fans is automatically increased to reduce the temperature. The fans and impellers can function at the higher speed indefinitely.
