The Best Liquid Cpu Cooler of 2018

10 Best Liquid Cpu Cooler

A Liquid CPU Cooler is a powerful cooler based on the proven principle of water cooling and is increasingly being used to keep modern processors quiet and cool. The individual components of a modern computer convert part of the electrical energy into heat, which is called dissipation loss. As the performance of modern processors increases, so does the heat generated. Where in the past the ambient air was sufficient to cool the individual components sufficiently, nowadays water cooling systems are increasingly being used to keep modern PCs cool. In addition to passive cooled PCs, where only a passive heat sink is used, there is also the active version, in which the heat sink is additionally supported by fans.

Active and passive Liquid CPU Coolers

Modern Liquid CPU Coolers are divided into active and passive coolers according to the type of cooling water recooling. With active cooling, a fan is used which generates an air flow through the heat exchanger. Most of these cooling systems are equipped with a relatively small radiator, which is available in a single, dual or triple version (for one, two or three fans). With the double and triple version, a higher cooling capacity can be achieved than with a single fan. In contrast to active cooling, passive Liquid CPU Coolers do not use fans. With the passive version, the cooling effect on the radiator is generated exclusively by the air movement through the radiator, similar to a normal radiator. In most cases, a passively cooled radiator is considerably larger than an actively cooled one in order to achieve a comparable cooling capacity. In passive cooling systems, the radiator is placed outside the PC housing to ensure optimum airflow. The radiator is available in two different versions, either horizontal or vertical.

Functionality of modern water coolers

The water in the cooling circuit is moved by a pump. In the heat sink, which is attached to the processor, the water absorbs the heat and transfers it to the radiator, where the heat is released into the air. If the cooling system serves several components in the housing at the same time, all cooled components are coupled in series to ensure a uniform water flow through all heat sinks. Nowadays, however, there are also cooling systems in which the pump, radiator with fan and expansion tank are permanently installed in one housing. With these modern systems only the heat sink has to be mounted on the CPU and connected to the cooling system with hoses. These modern systems, such as the ARCTIC Liquid Freezer 120, a powerful Liquid CPU Cooler with a whisper-quiet 120 mm PWM fan, are sometimes so compact that they can be installed quickly and easily in two to three standard 5.25″ drive bays.

 

History of CPU water cooling

The cooling of PCs with water in the private sector originates from some hardware enthusiasts who wanted to overclock their PCs as high as possible in the early 2000s. The popularity of Liquid CPU Coolers was also boosted by the introduction of the first dual-core CPUs at the turn of the millennium, which had previously only been used on high-performance servers and required a high-performance cooler due to the enormous power dissipation. At that time only air-cooled coolers were available, which had an extremely high noise emission and were considered annoying by many people. Initially, the first heat sinks for water cooling systems were manufactured in-house. These first models were extremely primitive, the water was pumped from a bucket placed next to the computer into the cooling circuit and returned. The next stage of development will be radiators and expansion tanks, which were built by the company itself and had different cooling capacities, each of which was adapted to suit personal requirements. Today, various high-performance Liquid CPU Coolers are available, such as the ARCTIC Liquid Freezer 240, high-performance Liquid CPU Coolers with 4 120 mm whisper-quiet fans or the Corsair CW-9060024-WW Hydro Series H80i V2 High Performance All-In-One water cooling 120 mm, which offer hardware enthusiasts outstanding cooling performance.
