Supercomputer cooling system is a unit of the Supercomputer which prevents it from overheating. Due to the white fog that appears when it rises it is likely the Supercomputer is cooled by liquid nitrogen. This program has only been seen in A Lack of Goodwill when X.A.N.A. William appeared on Earth and deactivated the system, causing the Supercomputer to burn up. However, Aelita managed to rectify the system before any major damage was done.
