Coolermaster Hyper 212 Plus - 1.8k [Moderate]
Thermalright Ultra 120 Extreme Rev. C - 2.5k locally & 3k online [but need to have a pair of good fans to Good results]
Based on the price per cooling, i suggest to get a CM Hyper 212+

If your budget can be increased then consider buying Corsair H50[3.9], Noctua NH-U12P SE2 [3.7k] or Corsair H70 5.5k
