We now have 2 AC's, temperature monitoring that send SMS's every 2 deg C after reaching 22 deg C (about 72 deg F), UPS and generator. But in the past we really had it bad on hot days (West coast, South Africa). What we have found is that an overheat of the server room causes hard drive failures for about six months. We now know that if it happens, we make sure that we have enough spare hard drives.
