you can either have the fan blow out the back of the computer, or out the top.... either way is perfectly fine. Some mobos have some pretty big cooling fins that may restrict you to one or the other, but normally any direction is fine.

It won't affect your cooling performance unless you currently have the fan blowing the hot air into your computer instead of out.
