Do I need liquid cooling for SLI?

[Caliaton]

Hey guys, I was planning on grabbing either 2 gtx 670's or two 770's in the near future for my new build, and I wanted to know if water cooling would be a necessity. Unfortunately, as of right now I can't afford to add water cooling, so I will have a cooler master hyper 212 evo. Will this be a good enough cooling solution? Also, can someone recommend me a great case for sli (good airflow and what not) around 100 bucks?
Any help is appreciated 😀

Okay so the CM Hyper EVO 212 is for your CPU and isn't related to the GPU selections that you have made. You don't need water cooling to run SLI/Xfire on the GPU's, just make sure you have good cooling in the case and you should be fine. The only reason most people want water cooling is to get higher OC'ing or a cooler/quieter system.
