That last post sounded like I was being a smartass and that isn't me so I am sorry about it, But as I said I think the two best heatsinks I have used on the 8KHA+ is the Swiftech and the SK-6, They are both good but I really like the Swiftec, Cost a lot but does a great job, I have never tried the Alpha as power supplys go I have used just about everyone on the market and the only one I have seen that will stay over 5 volts and over 3,3 volts under load is the PC Power and Cooling but it come with some noise, The Enermax is kinda cheap on it's IDE connections and I have had shorts with them other than that it is a pretty good not great power supply
