Over the years heat has progressively been an issue for computer enthusiasts. It still seems like yesterday that Intel's Pentium line was using brute force to keep up in the "Gigahertz War" and a massive amount of heat was the by product. Many companies have wised up in recent years by developing cooler and more effecient products (ie Intel and their C2D line of CPUs). While this certainly helps, heat continues to be an issue and always will. As more cases fill up with intake and exhaust fans, they quickly learn that a cool case has it's trade-offs. The more fans you add, the closer your case gets to sounding like a jet engine. This is where your friendly fan controller, like Zalman's ZM-MFC2, comes into play.
