Cooling power is substantial. When we used to rent space for SSC, cooling was charged for first. We got power limitations first, then cooling charge, then charge by power.

It would be better to have this heat used elsewhere, though I don't know how feasible this is. It's not likely to boil water, but perhaps greenhouse or something else. However, that doesn't necessarily help the data center survive, since it needs some cooling as well as heat dump.
