I got the perfect cooler for you. The Scythe Ninja 3. It's only like 45 bucks on amazon and it's one of the latest coolers from Scythe. I own it myself so I'm a little bias. But my prime95 temps at 4.7Ghz is only 74c. With intel burn in test they are an average of 80c. And that is really good for a 3570k at 4.7Ghz. The guy that built my CPU builds hundreds of them and he only uses the Scythe Ninja 3 for his CPU's. He also used Arctic 5 thermal compound. Which is also a good deal. Check out some reviews on it, they are normally pretty darn good and they compare to the higher end coolers, and for only 45 bucks you can't beat that. And it's really good looking, to me at least. And you can even get 2 fans for a push/pull setup for 7-8 dollars a piece.
