Leaf Spring Fan exemplifies that aesthetic design can also be functional. A quick look at the Leaf Spring, that it is obviously not your average case fan. Cooler Master designers departed from traditional thinking, by first using an S shaped stainless steel frame with airfoil to give it an aerodynamic touch. The fan also integrates a non-rubber design, which turns out to be a simple shock-proved mechanism; the result is reduced vibration and noise when building a complete computer systems.
