Optimal Cooling Config

Hello everyone,

I am trying to figure out the optimal cooling config for my case now that i am moving my GPUs to passive cooling, and want to just use case fan airflow to cool the components. I am currently using this case: http://www.newegg.com/Product/Product.aspx?Item=N82E16811147053 and i am using 2 Sapphire R9 270X in Crossfire and have this passive cooler on each: http://www.amazon.com/ARCTIC-Accelero-Plus-VGA-Cooler/dp/B0063VTXFS

I have the sidepanel 230mm fan taken off and have 4 120mm fans on there currently and want opinions on the setup. I am obviously going to have the 230mm on the front panel drawing air in, and the top 230mm drawing air out. The Rear 140 is being dropped down to the bottom to draw air in and i will be setting up a Corsair H80 on the back with a push/pull config exhausting heat from my FX 8350 CPU. Only reason i am replacing the side panel 230mm fan is because i think i can either have the 2 fans on the GPU (left side) draw air away and the other 2 draw air in, or have them all draw air in, or just keep the 230mm because it may be a few decibles quieter. What do you all think? Thanks. :)
 
Solution
Stock case fans run louder than my 760s fans almost all the time.
The way around the noise would be setting a custom fan curve, to low rpms, which would solve your issue. You just need alot of flow.

Um, What?

Your want your gpu's to be passively cooled by case fan air, which involves adding a massive heatsink? IN YOUR FULL TOWER CASE?
Why not just buy water blocks (full cover), 2 240mm rads and a few d5 pumps and 4 silent noctua fans?

But why does he want passive with case fans?

I used to use a full watercooling setup, but i do not have time or want to deal with water cooling on open loops anymore. I cannot see how the fans would be louder than the ones on the GPU+fan though because the smaller fans are louder than larger ones for one, and they move less air. plus with the heat sink so large, it will also have more area to remove heat from vs a normal GPU heat sink, there is definitely enough airflow to cool them though, and i could even throw a 120mm fan on the heat sink and keep it spinning at a low RPM to keep it cool if necessary. But yes, the one thing i cannot stand it the loud GPU fans.
