Like I see everyone who plan to buy CPU cooler buys Zalman which is bad for cverclockers, or something like that...
Zalman is popular because his coolers for graphic card which are good but on CPUs cooling space he fail, for many different things, one of them is his design who don't leads warm so good, and fan is very weak.
One of many good CPU coolers is TT Sonic Tower.It is passive cooler who has option to build in 120mm fan, Sonic Tower (with fan) results can compare with water cooling.
TT Big Thyphoon is also very good cooler,he is composed from two parts: 120mm fan and passive cooler. Ther are two version of Big Typ: VX and 120, VX has potentiometer and worse fan(louder),120 has better fan but he doesn't have potentiometer.
And GeminII is good cooler, GeminII is passive but you can put on it two 120mm fans which makes him very powerful, but his very big and heavy.
Hear some links where you can see some results of CPU coolers:
