Many repeater locations are very dirty. Running fans when there is
nothing to cool just circulates the dust and dirt and deposits more of
it inside your equipment. Many folks haven't re-discovered the
pressurized cabinet principle that we used to use all the time. Bring
air in through a filter and pressurize the cabinet so filtered air exits
through all the cracks. Minimum dust collects on the equipment and air
exhausting the equipment through all the cracks helps keep it out. Just
the opposite is true of the so called "modern day" computers. Nothing
like pulling unfiltered air in through every opening including disk
drives etc!
