Replacing/Upgrading H60 Cooling System Fans

My PC has developed an intermittent "chatter" that may be coming from my Corsair H60 120mm cooling system fan. Because my PC sometimes runs very hot due to the games I play, I am considering a higher volume cooling fan and the push/pull method. Any suggestions regarding the use of: (1) two H60 SP120L 2000 rpm pwm fans or (2) two H80i SP120L 2700 rpm pwm fans or (3) two Air Series SP120 high performance edition high static pressure (3 pin) fans? I assume (due consideration to Murphy's Law) that without fan control, I can mount the 3 pin fan on the 4 pin connection.

Thanks
