Yes, I did the same on my wet SS pin case cleaner by installing a salvaged fan out of an old vent hood. It blows air through the salvaged washing machine motor that now runs so cool you can put you hand on it. I built my cleaner then found it only takes 10 minutes to clean 3/4's of a gallon of cases to like new appearance so it's not like the motor runs long enough to overheat. Heat is the enemy of electronics so it doesn't hurt to do an overkill on cooling or at leas that is my excuse.
