As you've known by now, Zalman is a company who is very well known for its range of quiet cooling solution or Computer Noise Prevention System products or in short, CNPS. From the very initial review, we took a look at Zalman CNPS6000-CU and we're truly amazed how it cooled down our CPU testbed without making a single noise. Later on, we managed to experience and review more Zalman products and we did find that their products are truly and totally quiet without compromising performance.
