Hi David. Actually I wrote the text below. :) The fan I'm thinking of installing would be something like this: http://www.xoxide.com/yate-220-blue.html (or bigger), on one of the slider windows. But I see your point. Instinct (notice the distinct lack of scientific knowledge here <grin>), told me that the vent up top would be best. I was just trying to see what may work, and what may help others in terms of a user friendly install. For my needs, if the fan proves not so good, I can always use it to blow air around while sleeping. (I bet it's much quieter than the Canadian Tire fan I bought recently) And, I had wondered about aftermarket solutions. More Googling! Neil.
