I'm still planning out my build, I'll be going with Corsair's SP and AF fans. I've included a diagram of the air flow I intend on using and the fans. The AFs will all be 140mm.
The SP 120mm fans will be mounted to a Corsair H100i at the top.
I'll be taking out the bottom hard drive cage to get that bottom right corner unobstructed.
(Not a picture of my rig, just found one off Google for illustraitve purposes)
Yup, that'll be plenty of airflow. You wouldn't really need more intake in the front than the included 200mm. There is also a 200mm fan in the side panel of the case.
So far I have everything on that diagram purchased and ready to go except the bottom intake fans labeled AF14.
I was already deabting which size and style fans to use and if you're suggesting I might not even need them that's cool too. I was debating using 2 AF 140mm or 3 SP 120mm that are pressure optimized, like the 2 used in my H100i.
I am replacing the stock 200mm with a Cooler Master MegaFlow 200mm on the front of the case. I also bought a side panel from the Switch 810 with the bigger window and no side fan.
