I was talking to one of DC technicians about this and mentioned - hey, if a chiller ever breaks down (they are redundant), one can (even in summer), put radiators to max to help dissipate heat from DC rooms. He said yes. I asked whether this is some actionable item on some risk plans or whatever - nop, that is not something that we depend on. And it would just extend the time to do something but not prevent from overheating.
