A liquid CPU Cooler is one of the most common heat dissipation methods. It uses liquid as a heat transfer medium and can be divided into two categories: The first is an AiO (all-in-one) liquid CPU Cooler, which combines the water block and pump. The other one is a common liquid CPU cooler that only has a water block.
AiO liquid CPU coolers usually have a pump that is attached to the water block, and the water block is attached to the CPU. Then, it uses a flexible tube to transmit the liquid from the pump to the radiator. The radiator has a fan for heat dissipation.
There are no rigid tubes, so there isn’t any pressure drop which means that the liquid can dissipate heat through the radiator at its maximum flow rate.
However, it’s hard to install and maintain an AiO liquid CPU Cooler. Also, the radiator fan produces a certain level of noise. In contrast, common liquid CPU coolers only have a water block and a heat radiator. In this case, the water block is directly attached to the CPU surface. This design has a major advantage in that it’s easy to install and maintain.
However, it can’t have a high flow rate because of the pressure drop caused by the rigid tube which is attached to the water block. As the water moves slowly through the tube, its flow rate will decrease. Also, because there is no pump to drive liquid to the radiator, the CPU temperature will rise.
In summary, an AiO liquid CPU cooler has better cooling performance and is more convenient to install and maintain than a common liquid CPU cooler. However, a common liquid CPU cooler has better performance than an AiO liquid CPU cooler in terms of installation and noise.
In the past, the mainstream liquid CPU coolers were from Asetek, CoolIT, and Swiftech. In recent years, however, there has been a shift away from CPU cooling companies to manufacturers of computer hardware.
Things to Consider Before Purchasing:
There is a list of the things that we need to consider before going to the list of the top best Liquid CPU Coolers.
The radiator size is the most important factor in determining how effectively a cooler can conduct heat away from the CPU. The larger the radiator, the more heat it can absorb and dissipate.
No. of fans and RPM:
The number of fans and their RPM (revolutions per minute) also affect the CPU’s cooling. The higher the RPM, the more cooling capacity the fan has.
A liquid CPU cooler is more efficient than a heatsink and fan. If you want to know how efficient it is, divide the number of degrees of temperature drop by the power consumed. The higher the result, the more efficient it is.
The TDP or thermal design power is the maximum amount of heat generated by a CPU under a specific workload. It’s measured in watts. If a CPU cooler can cool a CPU at its max TDP, the better it is.
We need to consider the CPU socket that the liquid CPU cooler is compatible with. There are several types of sockets including LGA (land grid array), AM4, FM2, and so on.
If a liquid CPU cooler is compatible with the CPU socket, it will be much easier to install it.
As with any purchase, we need to consider the price. The higher the price, the better the quality. However, if you are buying a liquid CPU cooler for the first time, it’s better to try the cheaper one because it’s a good chance to check the performance and see if it’s what you really want.
After considering all of those factors, we can make a list of the top 8 best liquid CPU coolers.

Frequently Asked Questions
What is the finest AIO Cooler in 2021?
The best cooler of 2021 is the Cooler Master Master Liquid ML240P Mirage, which features a transparent pump design. Its build quality and features are to thank for this. The transparency of the pump enhances its appearance. It’s endowed with durability thanks to the twin tubing design. The pump’s side tubing and fitting may be rotated for convenience of placement. Because of the anti-vibration rubber pads and the square outer casing of the fan, it is a quiet water cooler. The blade rotates smoothly due to the case’s unique shape, which provides less noise.
Is it worth your money to purchase a liquid CPU cooler?
It is all dependent on your demands and requirements; liquid cooling is well worth the investment. Fans take up less room than liquid cooling systems. CPU and GPU are more effectively cooled as a result of efficient heat removal. They are noisier than air cooling systems because they remove excess heat through evaporation. Water cooling is ideal for high-end GPU users who wish to overclock their processors. The H150i Elite Capellix from Corsair provides fantastic, as well as inexpensive, cooling capabilities.
What CPU cooler should you buy in 2021?
The best CPU cooler in 2021 is the NZXT Kraken X53. It provides superior cooling for mid-range gamers with this large radiator. The CPU block has a larger surface area. It improves heat transfer and extends the life of the processor by increasing the CPU block’s surface area. With low noise levels, Cooler’s Asetek type pump delivers excellent flow and minimal noise. It’s waterproof and has a high resistance to abrasion, making it safe for handling and routing. It comes with a guarantee of 6 years, demonstrating the product’s excellent build quality and long durability.
Which is better, a closed-loop AIO or an air cooler?
In many aspects, AIO coolers outperform air coolers. They are more expensive than air cooling systems, but they are more efficient; for example, the Deepcool Captain 240 Pro V2 is a liquid cooler that even compares to air cooler in terms of efficiency and features. Water cooling has superior heat transfer capabilities than air cooling. They produce less noise than air coolers. They are more energy-efficient while also being greater heat dissipaters. High-end gamers/users get a larger overclocking margin from them.
