I have a window that has a window air conditioner in it that stays in the window all year around. This room is the hottest room in house on its own. Add that to the 3 Desktops, a laptop, soldering station etc and it gets even hotter. Add that to the fact that I usually have the door closed because I'm listening to music or using power tools like dremel, spray booth, etc etc. Needless to say the air conditioner doesn't work in the late fall, winter or early spring so I came up with this idea to cool the room. Its speed controlled so I can control the temp in the room better.
