I'm also using the Intel Core i series (unlocked version...specs are posted in another thread), and i purchased the Corsair H80 cooler for it. DAMN silent and easy install. It should fit easy into that Corsair case. Worth every penny IMO but won't shed $$ from your present cost list. The Coolermaster Hyper 212 i believe is still one of top budget coolers out there for $30 http://www.coolermaster.com/cooling/cpu-air-cooler/hyper-212-plus/
