These days, newer CPUs are producing fairly a large amount of heat when compared to old aged processors. This is due to the ever increasing processing speed and power. At the same time, we will never be satisfied with the processing speeds and always push the limits of the CPU. As we try to raise the FSB, we always get pulled back by the heat factor. The situation is worst for overclockers in warmer regions. In order provide better cooling capabilities, companies chose to design bigger yet better CPU coolers. But not all big CPU coolers can perform well and some might not even fit into smaller enclosures. This is where low profile CPU coolers come into play.
