Re: Mounting Fans on Top of Hood

There is no reason not to mount the fans on top of your hood if that is the
only place you can easily mount them. No reason to fight convection though,
so you would probably be better off having the fans blow *out from* the
hood rather than in to it. That way you are pulling cool air in the back of
the hood (and through every hole and crack), and pulling the hot air up and
out through the openings in the top.
