No you shouldn't. You can get a speed controller and turn them down if you want, but ur not gaining much....still gonna consume the same amount of power anyway. Watch the RH...it will likely climb way above 50% on you in a small space with no lights on....if you live in a dry climate you might be able to get away with it. Mine goes to 65% on humid nights even with the fan full bore and a miniature dehumidifier.
