There is nothing more pleasing than sitting next to your high end, top of the line, Billy-Bad-Butt PC. What isn't all that pleasing is the noise that your heatsink's fan gives off trying to keep your overclocked chip from bursting into flames (ok, so maybe it would just get too hot and lock up the system, but you get the point). I have long strived to find that one heatsink fan combo that gives good performance, but is also easy on the ears. If this sounds anything at all like you, than keep reading. If that 7,000 RPM fan in your case doesn't phase you in the least bit, I suggest you stop reading here. Today we will be checking out Zalman's CNPS 6000-Cu HSF combo in an ongoing effort to find a cooler which is easy on the ears yet doesn't lack anything in performance.
