HAF 912 case fan setup

[vlcmdude]

I'm curious what you guys think would be the best fan set-up for the Cooler Master HAF 912 case. I have 2x200mm fans and enough 120mm fans to fill every available fan slot, as well as a push/pull set-up on my Hyper 212+. I'm assuming that 2x120mm CM Blade Master fans would move a greater amount of air than 1x200mm CM Megaflow fan would. Currently I have 1x200mm fan on the front and 2x120mm fans on the top. Should I leave it the way it is, replace the 2x120mm fans for 1x200mm fan on the top, or get rid of the 200mm fans entirely? Will the difference in temp be noticeable at all? Thanks for the input.

What do you think about the 200mm vs 2x120mm in front or on top?

Currently I have 1x200mm fan in the front and 1x120mm fan on the side drawing air in, and 2x120mm fans on the top and 1x120mm fan on the back blowing it out. In addition to the 2x120mm fans on the cooler. This is my first build so I'm not 100% sure what proper airflow should look like.

Experiment as suggested.
I'd probably make use of the 2/200mm fans.
One in top and one in front.
Although 2x120mm would be ok in front.
Never had satisfying results with side panel fans but 1-2C temp decrease is better then nothing= never liked the extra dust the sidefan introduced
