I think the key here is that if your set point is at 80 F, you better be able to hit it with a unit down and you better be able to react instantly to any environmental failure. You just have no headroom to play with. Steven Naslund Chicago IL

I recall some evidence that 80+F temps can reduce hard drive lifetime, though it might be outdated as it was from before SSDs were around. I would imagine that while it may not impact the ability for a server to handle load, it may >reduce equipment lifetime. It also could be an indication that they lack redundancy in the case of an AC failure. This could cause equipment damage if the datacenter is unattended and temperatures are allowed to rise.
