I was under the impression that the altitude setting was manual, and was 
intended to help the system vary the fan speeds in line with the 
altitude.

There's something in the back of my brain about a bug wherein the fan 
curve wasn't quite optimised for certain hardware configurations, and so 
the workaround was to set the altitude to some higher number in order to 
force the fan curve to step-up (which could also then blow your PSU 
budget :))

But, this was all some time ago; perhaps it has changed in use?
