Your house isn't in the 80s-90s during the winter is it?
I live in the greater Phoenix area. For the next month or two, inside temps are likely to be in the 80s. In the spring, it will be back again. Come summer, inside temps in rooms where I might be able to store beer will probably see 90s 50% of the time.
I use a temperature controlled chest freezer for primary temp. I used an ice box and fan setup for awhile, but needed to upgrade to something easier.
