Best Fan Setup with Current Number and Heatsink

Hello, all! At the moment I have 3 case fans, 1 CPU fan, a graphics card fan. My new heatsink (CoolerMaster Hyper 212 Evo) has the option of adding another fan, and as such I am considering if I should move one of my case fans.

Here is my current setup:

And here is the potential setup:

To be clear, the yellow is my motherboard, the bottom green block is my graphics card (most of it is just a heatsink), the top green block is my CPU heatsink (it really is that big), the red is the fans, and the arrows are the airflow. I apologize for the amateur drawing, but it's the best I can do (ironic, since I'm actually a really good image EDITOR).

I would appreciate if you all would give me your opinions as to which setup would be most effective. The image is mostly to scale.

Adding an identical 2nd fan will net you 1 to 3C better temps.

Adding a second "whatever" fan can actually hurt temps.

Heat sink fans need to have high static pressure ratings to overcome the resistance of pushing air into, our pulling air out of a heat sink. And if you are using two fans you should ensure the two are either identical, or "play nice" with each other.

I recommend leaving your fans as the "current setup" shows. Or if you want the extra couple degrees, get another fan just like the one it came with.

Alright, I'll keep it as is. Thank you!
