The best would be a Noctua NH-D14 or Phantek PH-TC14PE or a closed loop Corsair H100 if you can fit a dual 120mm in the top (they need to be 15mm spacing from hole to hole)
For a low-end CPU like that i would recommend something Cheaper, the Coolermaster Hyper 212, you could find it for 20-30$ and it'll do really fine with this CPU as it's doing fine with I5 3570k I7 3770k at mild OC (4.2-4.4ghz)
If you go the liquid cooled close loop system (which i'm a fan of) just make sure your case can handle it.
I believe your case only has 120mm x 120mm exhaust ports. Most radiators take up allot of space.
Otherwise, as the above post mentioned, the Noctua NH-D14 is a great cooler
