New Upper Fan Module

I have redesigned the Upper Fan Module. This one has a sealed front so the air is drawn from the rear corner. 1/2 comes from the top and the other 1/2 fron the bottom to mix the air in the box to make it homogeneous.
The picture shows one for an aluminum scope, so it uses Velcro rather than screws for mounting, at the request of the owner.
Flat black for a finish to make it non reflective finishs the look.
What do you think of the new design?
I would appreciate a little feedback.

Hmm. That seems like it might be an improvement, Floyd. With the sealed front face, that is. You're bringing in cool air from above and below, rather than stirring up the air already hovering over the mirror surface. Did you try a smoke test?
I may need to add another fan, either above or below. I just can't seem to keep up with the dropping ambient air temperature. :S
