Liquid cooling systems for computers have become increasingly popular among PC enthusiasts and gamers looking to optimize the performance of their machines. A liquid cooling system works by circulating a liquid coolant through a loop that includes a pump, radiator, and a block that attaches to the heat source.
The heat from the CPU or GPU is transferred to the liquid which is then cooled as it passes through the radiator. This method can be more efficient at dissipating heat compared to traditional air cooling, which utilizes heatsinks and fans to manage the temperature of PC components.
