nestejäähdytintä

Nestejäähdytin, commonly known as a liquid cooler, is a thermal management device used to dissipate heat from electronic components. It functions by circulating a liquid coolant through a closed loop. The coolant absorbs heat from a hot component, such as a CPU or GPU, via a heat sink attached to the component. This heated coolant then flows to a radiator, where a fan helps to expel the heat into the surrounding air. Once cooled, the liquid returns to the component to repeat the cycle.

The primary advantage of liquid cooling over traditional air cooling is its superior heat dissipation capability. Liquids generally have a higher heat capacity and thermal conductivity than air, allowing for more efficient heat transfer. This can lead to lower operating temperatures for components, potentially extending their lifespan and enabling higher performance through overclocking. Liquid cooling systems typically consist of a pump, coolant reservoir, tubing, a water block (heat sink), and a radiator.

While effective, liquid cooling systems can be more complex and expensive than air coolers. They also introduce a potential risk of leaks, although modern systems are designed with robust seals to minimize this risk. Maintenance may involve topping up coolant levels or cleaning the radiator and fans. Liquid cooling is widely adopted in high-performance personal computers and servers where thermal loads are significant.
