I actually do have a basement, I guess I'll just have to put a thermometer down there, because I'm a horrible judge of temperature.

But thanks for all the advice on the powered cooling devices! I was thinking of incorporating something using heat sinks from a CPU, but couldn't envision how it could work.

The humi's been down there a while, and the humidity has stayed at my desired percentage. I will find out temperature this weekend and see. It's fine now, as seeing the mid-50's is rare here these days outside in the middle of the day, but summer is coming. Just wanted to be prepared. Plus, projects are always fun.
