i have a corsair air 540 case.i am going to use 3x120mm at front as intake 1 corsair air series AF140 at back as exhaust.will use the nazxt kraken x61 in push/pull configuration at top.i will use corsair sp 2x140mm as push but what should be the other two(which will be used as pull)??the fans that came with the kraken or the ones that comes with the corsair air 540 case??
in one word which one is better Air Series AF140L or NZXT FX V2 140mm??

For push pull you really should use the same CFM fans, if you use 50 CFM fans pushing and 80 CFM fans pulling the their were really no need to even install the 50's.

and which one should i use??i understand that i use fans of same cfm for push/pull that means i have to use the kraken fans.but if i use those AF140 fans what will be the result better or worse??

If their the same CFM it really makes no differance. You can look at the DB level and get the quitest.
