Questions about fans+sizes+air moved

HI, I had some questions about case fans.

 

 I was wondering if a 200mm fan @ ~580 RPM can move more air than a 120mm @ 1500 RPM.  Yes I understand it's louder etc etc, but does it move more air? I have a leftover noctua nf-f12 I need to put to use, and I want to use it seeing as I can plug it into corsair link 2 and control it.  

 

The 200mm fan is on my sidepanel as an intake blowing onto my graphics cards, but if I put my hand infront of it I barely even feel anything

I can't think of any easy way to measure the difference, since there are so many other variables other than just size and RPM. Although, considering the 120mm is running almost 3x faster, it most likely is moving much more air.

Thanks, I took my 230mm, turned it diagonally so it'd fit on the side panel that's meant for 200mm fans, and replaced my front intake as the extra noctua i had laying around, I also made the 230mm an exhaust instead of an intake.  GPU #1 is around 5 degrees colder now. Happy as heck with the results
