no you dont need any other cooling, if your OCing, which i doubt you are, then you need it.
i have a question, do you no ANYTHING about your current motherboard? why does a motherboard have to be newbie friendly? if your a newb, then you clearly have no business fiddling with it ( bios whise, not building your own computer). I would strongly suggest for the DFI. or if your going with Asus get the A8n SLi Premium, anything else is not so great.
