Welcome skydiver......

It is probably gonna take a couple of weeks before they reach the RH that you want. Alot of people do prefer there smokes to be at 65% (me also), so having them at 62% is not so bad.

Good move getting the 110 Qt cooler, especially if you plan on sticking around here. I have a 54 Qt thas packed, I'm waiting for my cabinet humidor to arrive.

As for the air circulation.... you can by one of the Oust Fans. They run on batteries and turn themselves on and off. http://www.oustodor.com/oust-fan/ Just make sure you don't put in the air-freshener.
