I think there is plenty of air movement over the fins. I've often
thought of putting an auxillary fan (solar powered, cause that's when
the fridge needs the assistance most) in the access hatch for the vent
stack.

It's been my experience that I get a fair amount of warm air moving up
on the back side of the stove, but that it is partly hindered by the
curtains (and stove top when open). I figure that the access hatch grll
is near enough to the top and than an auxillary fan blowing the heated
air out at the point can only help.

The only reason I haven't followed through on this (outside of
laziness), is the pain of carefully running the wires so that they'll
be (mostly) hidden. Putting the solar sell on the poptop works out
pretty well too as the angle of the poptop (if I park correctly) lines
up the solar cell with the sun better.
