Quiet, cool

It's cooled down here substantially over the past week; it's down to 50, and the highs for the next week are all in the mid-60s. I'm trying things out with no fans running now. The fans I bought to help circulate air were very quiet as fans go, but right now the house is almost totally silent—all I can hear is the computer and my own breathing and keystrokes. No house noises, no neighbor noises, and no road noises. It's eerie.
