I have been looking for quietness as the main issue since im nto overclocking at the moment (may in the future)
I gave my computer to a palce for fixing a couple of problems though and am getting them to change thef an as well. Unfortunately they don't have the arctic cooling in stock, and will get it "some time next week" and they don't keep the ninja plus. I'm in a kind of a hurry to get this comp back, so i've decided to go with the Zalman 9500 since they do have that. I'm not sure how noisy it'l be, but I might pick up the computer tomorrow and i'l liten to it then. I've got 2 7950 GX2's as well in the rig, so if I can't hear the Zalman over them, it should be ok. I read somewhere that the 7950's operate at about 40dbs. Since the Zalmans under full load are 27.5 (not sure about this) and 18 at low RPM, I think it should be ok.
My dad got fed up with me over-analyzing and over-thinking things, so he's told me to go and get the zalman fitted, and if i'm too unhappy with it, then get the arctic cooling. I'm not too happy with that solution since it involves wasting some money, but yea, my dad's gotten pretty fed up
At any rate, thanks for the help everyone

And if someone has some re-assuring things to say about the Zalman, that would be nice ^_^
