hi,
i cut out the aperture and placed two evercool fans into it, perfect fit.
high and low knob at back of box, am i missing something here?
most of the cool air blows outside the box not in the enclosure.
any help appreciated from anyone who has used these fans in there build.

You want the air to blow out of the box. The idea is to draw fresh air in through the slot you will have by your LCD so the air cools it as it is pulled toward the fans and out the box.
