I am purchasing a 5820k and a x99a or x99s, and I plan on streaming games such as dayz, Overwatch and CSGO. I plan on Overclocking it to 4.3 GHz, but there is one issue. I have a hyper 212 evo as my cpu cooler for it, and I am not sure if this little $25 cooler could be enough to keep the beast cool. I do not know which would be better for me in this case, an s340 or an enthoo pro M. I would like to know if 5 case fans + whatever come with the case and the hyper 212 evo would be enough to cool my cpu.

Extra info
Motherboard: Msi X99s or X99s Sli PLUS
GPU:gtx 970
Ram: Corsair Vengeance LPX
PSU: EVGA SuperNova 750 watt gold

Edit: I would also like to know if using a X99a or X99s would have any differences. Money is very tight, so any money I can save is a bonus.

How well a CPU overclocks is ultimately up to luck-of-the-draw. It may be the exact 5820K you receive will not budge over stock at all, it may be that it can hit 4.7GHz on an Evo 212 and 5.2GHz with liquid. Either one is possible (not likely, but possible).

That all said, you can mainly ignore case fans for this calculation. All you want is a CPU cooler that can handle the amount of power being dissipated by the CPU, which you won't know a priori. However, what you do know is that certain coolers have better ability to handle heat than other coolers. This is measured by degrees per watt. You can go look up what an Evo 212 is rated, and what the maximum load it is rated for actually is. Then you can attempt to estimate the CPU...

You can go look up what an Evo 212 is rated, and what the maximum load it is rated for actually is. Then you can attempt to estimate the CPU power - remember it's TDP * overclocked speed * overclocked voltage ^2 / (stock clock * stock voltage^2).

Case fans serve only to reduce the case temperature, bringing it closer to ambient temperature of the room. With better case fans, you would lower the case temperature by several degrees which ought to lower the CPU temperature in the exact same way. A few degrees is rarely the deciding factor between a stable or unstable OC - plus, you don't want a system that runs fine in summer with the air conditioner on but crashes in winter with the heat on.
