window fans for cooling?

[fishface]

so i got one of these today, not the one shown in the above link but it rocks. i put it behind my canopy and it's dropped my temp down and holds it at 78.5f. waaaaay better than the old clip-on deal i had. i've been having a bit of a difficult time dealing with high water temps so far this summer and really didn't want to go the chiller route...this has been a very inexpensive alternative for me.
