I just came across Frank Condelli & Associates article on fridge maintenance (See http://www.frankcondelli.com/fridge.htm ), and one of the upgrades they recommend is to put an exhaust fan for the fridge in place of the city water hookup (or cut a new hole if you use that hookup).  The idea is that this will vent the heat from the fridge outside rather than inside, which is the current setup.  My questions is has anyone done this?  What size fan did you use and where did you find it?  Was it worth the effort?

Thanks
