I'm planning a build in the Corsair 350D and I want to replace the fans with two 140mm Cooler Master fans for intake and three 120mm Cooler Master SickleFlow fans for exhaust. Question is, would this setup create positive pressure inside the case? Also, any thoughts on my choice of fans? This is my first build so I'm not very experienced when it comes to case fans. Thanks!
if you get a fan controller for them all you can set the air flow to what ever you want. just find a good one at a decent price and call it good
You shouldn't need a fan controller, as long as you purchase a decent motherboard. You are not using enough fans to warrant a fan controller. I recommend trying the fans that come with the case before spending any additional money on fans. The 350D has some great stock fans.
If you need anything additional; I suggest these:

Yeah, I only really wanted the 120mm fans for aesthetics/lighting, and I just wanted the two extra 140mms so I would have the exact same front fans for the intake.
