Well, that heatsink needs a lot of airflow to be really good, so if you want performance and silence, it isn't going to happen. However, a decent 25-30 cfm 60mm fan should work, like
this one perhaps or maybe
this one
However, a 1.4TBird puts out a great deal of heat, and with a low cfm fan, you wont be able to keep it very cool if you pan on overclocking. However, it should do a fairly good job and will allow you some headroom.
