Yes indeed. Sometimes they're so loud he wakes himself up. :)

But, rather than trying to control temp with evaporation, why not simply
install a thermostatically controlled electric heater element in (or
against) the manifold. Hot day, low down, it's off. Cold day, high up it's
on full. Want the EDDIE at a lower rpm today? Turn the thermostat up (or
down).
