How do I reverse my PC fan direction?

What happens if you reverse case airflow?

If you were to reverse the airflow only in your case it would have an intake right next to the exhaust (the top rear case fan blowing in, and the power supply blowing out.) This would cause your case fan to pull hot air from the power supply back into the case then blow it onto your cpu.

Is one exhaust fan enough?

Having at least one intake and one exhaust fan should provide a substantial temperature decrease versus having no fans at all.
