I understand what you're concern about keeping your sticks in a 55 degree temperature. I think, however, that you are discounting the containment capabilities of the cooler itself.

Essentially, you're creating an independent environment; one reason why coolerdors are such an attractive option is because they protect the contents from outside elements. I would think that within the humidified confines of your coolerdor, you'd be able to sustain a humidity, and eventually a temperature, that would be desirable. So, while the temperature outside the coolerdor would be around 55 degrees, the actual temperature inside the coolerdor would be what you were looking for. I had a similar question about keeping smokes cooled in a coolerdor a little while back - I seem to remember getting the suggestion that if I wanted to stick a frozen blue ice pack in there occasionally, that would be okay, but generally, kept in a cooler spot of the house would benefit me. And we're talking about cooling to 70 degrees from 100 degrees - I would think dropping 30 degrees would be more of a concern than raising 10.

A cheap and easy way to test this would be to setup the coolerdor as directed in the "build a coolerdor" thread (should be a sticky in Accessories), but include a small thermometer in there as well. You're coolerdor may do a better job holding humidity when it's more full, so you might want to take that into consideration. I'd hate to see you spend all that money when a cheaper solution may be available.

But I DO hate you.
