Ultra-120, P180 fan orientation

I'm finally getting my new rig together, but I'm trying to figure out how to orient the YL fans I have in my P180. I have it set up like this currently:

Front bottom - empty
Front top - 120mm antec intake
Top - 120mm YL exhaust
Back - 120mm YL intake

The back fan is what I'm waffling on. I have a 120mm YL on the Ultra-120 pointing straight up towards the top exhaust. What's best for max cooling?
 
You want the ultra-120 to blow air towards the back fan, which will be HOT air, then you want the back fan to EXHAUST that HOT air out the back of the case, so I'd say change it to intake. I would also place an intake in the lower middle, to cool your HD's, just put it on low, which should cause enough airflow. The rest of the airflow will be generated by the PSU. If you got another YL left then remove the middle HD bay, and place an intake fan there, it will supply your videocard with fresh air.
 
I don't really understand. My heatsink fan is not pointing to the back of the case, it's pointing to the top. I don't know what the "lower middle" is, but I already have a fan behind the top filter door blowing in as an intake.
 
Make a picture of your case, this is getting confusing indeed. I only know of HSF with the fan either blowing air towards the back of the case, or blowing air down on the motherboard, like the stock AMD cooler does.

And lower middle is the one between the PSU area and the harddrive cage? And yeah, the top filter door fan is where the other HD cage is.
 
I have a fan in the lower part of the case (between the HD and PS) pulling air from the front outside across the hard drive mounted in the lower area. The back fan and top fan are pulling air out of the case. And I added another fan to the mid front area to pull air in from the front which blows across the vid card. This keeps my case very cool and allows the air to flow through the case from the lower front to the upper back. This makes the most sense to me.
