The liquid-cooling systems also called water-cooling systems are upgraded less frequently and evolve even slower than the air-cooling products. There are several reasons for that. First, liquid-cooling system components that have been matched well and are put together properly are always more efficient than even the most advanced air cooler. In addition, systems like that can cool down several different components simultaneously. It means that they aren’t really direct rivals to air coolers and therefore the competition in this market segment is way less aggressive.
