Darwinism has also been referred to as ?adapt or perish?. It exists not only within nature, but within consumer products. Essentially, companies must change their product line to meet the needs of the consumer or they will not be purchased. Which, in turn, will cause the product line or company to perish. While things looked bleak for air cooling for a short time, the adaptations of top tier manufacturers made it once again the go to choice for reliability, effective cooling, and low noise. However, a more recent change in the size and shape of builds has forced a slew of new smaller coolers to market, and has set up a need for better component compatibility across coolers of all sizes. We are seeing the first PCIe slot more commonly used, and this largely ignored space has commonly been the home of fin stacks in coolers. Companies like Noctua are adapting with high compatibility products such as the new NH-C14S CPU cooler.
