the big typhoon will definitely be good for cooling. Its a great cooler that performs hand in hand with the Ninja. The only problem with the typhoon is that its so big, the 120mm fan is going to be real close to the side panel on your case so it might not be able to pull as much air as it is supposed to.
to answer Kitire's question, for under 25 bucks a good cooler is the Arctic Cooling Silencer 64 ultra but im not sure how much you can overclock with it. It real quiet though and better than stock cooling. its only about 19 bucks here: http://www.shoppts.com/arcosi64ul.html
or you can pick up an older model of this cooler at New Egg for even less: http://www.newegg.com/Product/Produc...2E16835185110.
This would be a quiet solution but i would not recommend to overclock using this cooler.
