I have nothing to add to the wine cooler topic, other than when I was in France my family stayed with a family we had done an exchange program with through school and we went and stayed a night at one of their friends houses out in the country. That guy was a hardcore wine drinker, had a wine cellar in his house, and had even started making his own wine. As far as I could tell, the purpose of the wine cellar and I'm guessing the wine cooler, is to keep the wine at a certain temperature and humidity, without it being subjected to the temp and humidity changes throughout the day. If that's the case, then I would guess a fan to circulate the air would be somewhat counterproductive unless the unit had something in it that also actively regulated humidity. Then again, I could totally just be talking out of my a$$.
