Liquid cooling is a radiator for the processors inside a computer. Like an automotive radiator, a liquid-cooling system circulates a liquid through a heat sink attached to the processor. As the liquid passes through the heat sink, heat transfers from the hot processor to the cooler liquid. The hot liquid then moves out to a radiator at the back of the case and transfers the heat to the ambient air outside of the case. The cooled liquid travels back through the system to the components to continue the process.

Over the years, CPU (central processing unit) and graphics card speeds have increased. To generate the new speeds, CPUs employ more transistors, draw more power, run at higher clock rates, and thus generate more heat than ever before. Liquid cooling is more efficient than traditional heatsink technology at moving heat away from components.

In turn, this technology allows processors to run at higher speeds by keeping the CPU and graphics cards running within the manufacturer’s temperature specifications. This efficiency is one reason extreme overclockers tend to favor this approach—in some cases, doubling processor speeds using very complex liquid-cooling setups.

Another benefit of liquid cooling is quieter operation. Most current heatsink-and-fan combinations generate a lot of noise because their fans work hard at circulating large volumes of air. In fact, many high-performance CPUs require fan speeds in excess of 5000 rpm; overclocking a CPU requires even more airflow over the CPU. Liquid cooling reduces the “engine noise” this generates.
