Hyper 212 Evo + Coolmaster Sickleflows x 2 is around 48 dollars. I personally don't recommend the stock fan unless you want to keep it at stock clock. You always wan't to match fans on a heatsink, the best bang for your buck are the Sickleflows.
For 10 dollars more you can get the Noctua NH-U12P SE2. The build quality is better and it comes fully equipped with everything you could possibly need. Including 2 of the best fans you can buy, which usually cost $25 each by themselves.
However the Hyper 212 Evo w/ Sickleflows will perform just as well, but the Noctua would come out with a slight advantage, ESPECIALLY when overclocking.
The choice is yours, however the Noctua colors are kind of ugly. I personally went with the Noctua U12P, because my case does not have a window. I got it for $54.95 on amazon with free shipping.
