Dude... I got a very similar setup with an i5 3570k overclocked to 4.1Ghz in a CM Storm Enforcer chassis (it was not that cheap when I purchased it back then). My temps were not so great either. I initially replaced the stock cooler with a 212X which provided ample cooling running the cpu at stock. This is a great cooler to replace the stock one, as suggested by the previous comments. I recently decided to OC the cpu a little, then picked up a closed loop cooler for around R1.2k to provide enough cooling to the cpu under load. Really makes a difference in terms of cooling and noise reduction! The biggest problem I faced is that it's great to have good air flow with fans galore but it usually comes at the price of your pc sounding like a Boeing 747, so don't forget to consider that unless you're okay with it.
