Well, right now I'm running a 3b1, 3.5Mb RAM, 67Mb HD in an unairconditioned apartment in a two floor duplex. There are trees and such around the south and north sides, an apartment on the north side, so sunlight only seeps in after about 1800hrs. I have a window fan that sucks air through the house at a pretty nice clip. Avg interior temp is probably around 90F or so. About once every hour or so, the fan kicks into what sounds like high gear for a few minutes. I've had no overheating problems of any sort at all. I keep 2 in open on the right and left sides, 8 in in the front and back. Airflow seems to be good, but there's a lot of dust in this old house, so I have to open it up and clean it out once every now and again... :-( Hope this info was useful to someone. -- Skate UNIX or go home, boogie boy...
