Here's a question for the admins out there, our server room has 9 dell power edge somethings anyway we have a air conditioner that runs 24/7, well the guy I work with has half the ceiling tiles removed so from what he says the air doesn't become stagnent, well I say isn't that what a air conditioner does, pulls the warm air out of the room which makes it cooler. I say put the tiles back in and seal the room tight and let the air conditioner do its thing, any links to prove my case would be great. Thanks
