Coolermaster V8 isn't that good and is very expensive. A Z600 is often better for a lower price. It's never the best possible air cooler. (yes I know him, my friend got it and reviewed it for a website). I don't know exactly if it's loud or not... My recommendations: Low-budget: AC 7 Pro Silence + performance: Scythe Mugen Great performance: Z600 (+ 1 or 2 120 mm fans) When you don't care about money: get a WC Maybe you can even run that system on a 300/350 watter. When the 12V+ rails are good, you are fine. Your Enermax could easily feed that components, even when you put a extra 8800GT in it (but you don't have a SLI motherboard ).
