No, it isn't. Your fans are switching into overdrive as a last-ditch effort to keep the system from burning up. What your going to need to do is install a large vent in the door of the closet, and a number of fans behind it which draw the cool room air in, and the pressure will force the heat out through the hole in the ceiling. APC makes a temperature sensor that plugs into a card that installs in it's UPS, and can be queried by apcupsd connected to the UPS via serial cable. That might be an answer if your powers-that-be need some sort of proof that your burning up your servers. My personal inclination if I was in your shoes and my bosses were shoving the gear into the closet, would be to say nothing and just let the shit burn up.
