My experience is that electronic/computer type equipment runs best when it
is in a cool environment, i.e. too cold for a human in T-shirt to work in
for very long. And when the ambient temperature gets above room temp, then
you get too many wierd and unexplainable problems occurring or just plain
equipment failure. Sean Donelan is right to worry about condensation and I
believe that you should maintain a fixed humidity level in the air in your
facilities. Keep the temperature below 18C but not so low as to cause
condensation. Get some Compaq engineers to recommend a humidity level and
ask your HVAC peopel to keep it constant. In Palo Alto this will probably
mean adding humidity in the summer and removing humidity in the winter. In
the Northeast you would need to do the reverse.
