vesijäähdöt

Vesijäähdytys, known in English as water cooling, is a method of cooling electronic components, most commonly a computer's central processing unit (CPU) and graphics processing unit (GPU), using a liquid coolant. This liquid, typically distilled water mixed with additives to prevent corrosion and biological growth, circulates through a closed loop. The process begins with a water block mounted directly onto the heat-generating component. The coolant absorbs heat from the component through the water block and is then pumped to a radiator.

The radiator, a network of thin fins and tubes, dissipates the heat from the coolant into the surrounding air. Fans are often attached to the radiator to accelerate this heat transfer. Once cooled, the liquid is pumped back to the water block to repeat the cycle. This continuous circulation allows for more efficient heat removal compared to air cooling, especially under heavy loads or when components are overclocked.

Vesijäähdytys systems can be either custom-built, allowing for flexible component selection and aesthetic customization, or pre-assembled all-in-one (AIO) units that offer simpler installation and maintenance. While generally more effective at managing heat and often quieter than air coolers, water cooling systems are typically more expensive and complex to install, requiring careful assembly and regular checks for leaks.
