Unless you have an actual condenser unit (like in fridges or A/C) or moisture absorbants (like silica gel) it seems rather a gimmick as the surrounding level of moisture is not decreased and blowing more moist air over components seems rather not beneficial. Remember that corrosion in electronics is typically electrochemical oxidation, therefore it needs reactants to occur. Since V is sealed inside, if anything it will be more resistant to corrosion v.s. actively cooled systems. Of course if you subject any electronics to harsh environments, they will likely fail prematurely, and V would not be any different.
