Hi, I'm new to this forum and also to building PC's. I have this list that I put together here http://pcpartpicker.com/p/j6KxD3, it's a three monitor build. I'm wondering if the cooling fan I have would be sufficient enough to cool this build or if I should buy a different one and if so which one, or should I go with liquid cooling and again if so which unit would be good for this build. Also would over clocking do anything for this build or would I be better off not over clocking? If possible would like to keep the build under $4000.
