Future archeologists will know this was an important cooling system. Because of the pedestal.
How do we know about Zeus and Apollo? Someone put them on pedestals. How do we know about Dante's Beatrice and Beth from "Beth"? Someone put them on a pedestal. One of those pedestals might have been higher than the other one, but you still get our point. The curious seekers of tomorrow will know how important this cooling system was to you, because they'll see the pedestal. That's just how it works.
