Pick your server, go to product info and tech specs. That shows the temperatures.
If you have a small room, there is good news and bad news. The good news is that it shouldn't take much to cool off a small area, the bad news is, if you have a sizable server, it will put out quite a bit more heat. You could look into wall hanging units for the comm room. They run roughly around $2K-$4K installed. Contact your local airconditioning maintenance company and they will give you free quotes.
I am having the same problem with my comm room. The controllers decided not to include my air conditioner when we remodelled and it is constantly around 85 degrees in there. We lost a power supply in our Citrix Server. It cost as much to replace the power supply and completely rebuild the server as a conditioner.
Hope this helped.
