A 220VAC run on 120V will do the same trick. Moves air and is relatively quiet. Lots of 220V fans at the flea markets for cheap.
Fans should generally be mounted in such a manner as to take advantage of any natural convection. A perfect location is above the cage for the finals pulling the air up from the final and exhausting up, and not blowing down. 73 Gene K1NR On Fri, 29 May 2009 12:32:55 -0400 "Kris Merschrod" <[email protected]> wrote: > Yes, by all means draw the heat away.
