I don't know if you remember this little science bit, but hot air rises.

For effective case cooling, you want intake in the front (and side, if you have it) and exhaust out the rear (and top, again, if you have it). Almost all fans you buy should have some arrows on the side indicating the direction the fan spins and which way it's blowing.

When properly setup, good airflow will keep other components in your computer cool and *may* help the CPU temps. Just keep the direction the same (ideally, front to rear), and you should be good to go.
