the FX series coolers I've used are loud and not very efficient. you will be stuck with stock speeds unless you want to hear a wind turbine blowing out of your system, and even then it will be very warm @ or above stock speeds. that TX3 seems to have slightly better specs(higher RPM and airflow), but at the same time smaller fans than the 212 Plus\EVO so it SHOULD do a nice cooling job. add a second fan for the push\pull setup and it should work okay.
i would personally stick with the 212 series if you have the room.
