    That's right, it was not obvious! Good thinking. But the exit holes should be a little bit larger in my opinion. The resistance encountered on having the air exit will cause the fan to work harder, possibly hurrying along it's demise. Might I suggest that you add additional exit points on the bottom of the case and raise it up on "feet". Then the exhaust ports could be hidden.During the course of my career with the government I had many instances where proper ventilation was not thought of and subsequently caused heat related problems. Even now, in my retirement job, I have encountered similar, but unfortunately, they are not ready to change and consequently problems occur. So I just keep fixing and replacing things when they overheat. Overall, quite a novel and interesting ...

    A fan is a good idea, but if it is blowing out, where is the air intake? That fan will spin real pretty when it isn't actually moving air. You may even detect a faint sensation of air movement, but for better movement, you should have installed another hole with a dust screen on it so the air will be drawn in the cavity by the fan pushing the air out.

    well not exactly related to this class, I had to to add a connector to a temporary battery to work with a camera. Attached is a scan of the two wires, soldered with heat shrink applied.
