Working principle of CPU cooler

The working principle of air and liquid CPU coolers is similar, and their essence is the same: they absorb heat from the CPU and then dissipate the heat from the hardware. The heat generated by the processor itself is dissipated onto a metal cover called an integrated heat sink (IHS) on the CPU. Then, the heat is transferred to the substrate of the CPU cooler. Then, the heat is dissipated through the liquid or heat pipe to the fan, and then blown away from the cooler before finally leaving the PC. Although the basic mechanisms are similar, the ways in which these two methods achieve heat dissipation are very different.
