So basically this is my first time building a Gaming Computer and I have no idea if I'll need a cpu cooler for my i5 if I'm not going to be overclocking. And all I plan to play games wise is GTA 5, when it comes out, Battlefield Hardline and CS:GO, so I'm not sure if ill be able to run these games at fairly decent settings without my room being excessively heated and my cpu overheating. If needed I can respond with my specs.
