I really like my HAF. I have had it almost a week now. It is no louder than my old Sonata II was. I do hear it, but it is a very low sound of air moving. The thing really does move air well. With a S1283 my E8400@3.6 idles at 32 and loads at 45. I was considering a P182 also for the looks and the quiet factor, but I opted for the HAF based on the cooling, space, and cable management.
