I will walk through walls of fire for a 1 degree change in temperature. If it were not for my wife, I would run the room airconditioner in my personal study (a small room with a 12,000 BTU wall unit!! ) in the middle of winter where it is -5 degrees F outside, just for that extra lower load temps.
Man your stuff better come pretty damn fast at stock to need a 12k BTU AC to keep it cool...
