depends on your cooling situation already going on in the case. In most instances, facing the psu down will help it stay cooler by not sucking in already hot air thats in the case. If you don't have a lot of cooling at the bottom of your motherboard, it could help the lower slot components dissipate heat better if the fan is facing up, but it will make your psu run hotter and less efficiently. However, if you have your case on the floor and the fan is facing down, it may want to act like a vacuum cleaner. It's a trade off either way.
