lol well I've got 7x80mm fans in case! 4 front, 1 side, 2 rear! I dont hear it much! if you do you just need to turn up the tunes!!!
it completely depends on the specific fans, some 120s will be more effective and quieter, but 2 80s could be more powerful and quieter.
thinking about it the main things that will affect the fans are:
-size of the blank spot in middle where the motor is
i think overall the 80s would be the better option, because the size of blade area and blank spot must be pretty similar in 2 80s as in 1 120. so the high rpm being the reason id go with 80s! but if you fear "insane hornet" well might not be best option
if you can get detailed specs of the fans and compare! but improbable!
hmmm this post has developed with thought lol
