If you run your data center in the 80s instead of the 60s, you get a 
considerably shorter lifespan on your hardware.  Great decrease in MTTF
mostly due to capacitor failures but also CPU failures to a lesser extent.

But, many facilities replace their servers on a three-year cycle anyway, so
the shorter lifespan isn't much of an issue for them.  Their systems don't
need to last very long anyway.

In some climates the cost savings is dramatic and more than makes up for
the cost of a reduced replacement cycle.

Of course, this all goes wrong once you start talking about anything other
than commodity servers.  HPC systems, big shared memory machines, or people
forced to run older hardware definitely want to keep the temperatures down.
