The latest conversations I've had with our server HVAC guy was the current thinking is that as long as the intake temp on each server is below 80 then it will be a non-issue. How one goes about achieve that is your choice :-)

Tell your boss it is like running a temperature yourself. You can survive and function at 104 degrees but you are miserable, you don't give accurate information, and you are sluggish. You could possible slip into a coma if your temp goes up a degree or two and you could lose brain function and memory loss. If that is what he wants by saving a few dollars then yeah raise. Hell shut it off and hope the internal fans keep it cool enough. If the AC is pulling to much power maybe a wiser approach is to get an energy efficient AC unit... Just my thoughts. ----- Original Message ----- From: "Steven M.
