I have a recessed shelf which holds three components that each generate heat:
- A projector
- A computer
- An audio power amp
The shelf is located at the top of the wall and open at the front but closed on the 5 other sides. Because of this, the airflow created by the component fans is simply not enough to cool the space and things are beginning to overheat.
I'd like to install a fan to cool the space but not sure what the best placement and airflow direction would be to cool the space. One consideration is the direction of the existing projector fans which create a bit of an airflow pattern on their own. I'd also like to keep the heat inside the house since it's beneficial in the winter.
My question is basically, what is the optimal direction and placement of a single fan in order to exchange the air and cool the space?
EDIT: To clarify, I intend to cut a hole in one of the existing surfaces and install the fan to move air between rooms, and not just to blow air around inside the shelf.
