Buying Guide:

In the past, CPU liquid cooling was not a necessity. However, CPUs nowadays generate so much heat that they require water or air to be cooled. The best CPU liquid coolers are those which can dissipate heat quickly and efficiently while using less energy than other methods. This buying guide will give you some advice on what to look for in your next purchase of cpu water cooler.

Size:

Size is an essential factor to consider when buying any CPU cooler, but especially with water cooling equipment. CPU Coolers usually come in 3 sizes, i.e., 120mm, 240mm, 360mm. There are other sizes such as 140mm and 280mm, but they aren’t used extensively.

 If you buy a 120mm liquid cooler which has the same size as your processor, there will be no problems fitting it into place or attaching it properly to your motherboard. However, you need to keep in mind that there are certain limitations with smaller CPU coolers. For example, 120mm liquid coolers cannot be used on processors with a higher wattage than the cooler is rated for. On the other hand, If you plan on overclocking your processor, it’s best to get something larger, like a 240mm Liquid Cooler.

Quantity of Fans and Radiators:

The quantity of fans in a Liquid Cooler is another crucial factor to consider before making your purchase. The number and types of fan that comes with the CPU water cooling equipment can significantly impact how well it performs when under heavy usage. 120mm liquid coolers usually come with one large fan and 240mm or 360mm Liquid Coolers come with two or three fans, respectively. The larger the size of the fan blades, the better cooling potential they have at low speeds.

On the other hand, 120mm liquid coolers usually only contain one radiator, whereas 240mm Liquid Cooler will either have two or even three radiators depending on its design. Some 120mm Liquid Coolers may also include more than one set of tubing as well as pumps. So it’s important to consider everything before making your purchase decision. You will have to find out what size your CPU is compatible with? Also, how much fan power does your system require?

Type Of Tubing:

The type of tubing used in a Liquid Cooler has an impact on the performance as well as its installation. Plastic tubes are less expensive, but they can also create air bubbles that cause problems with circulation. However, if you opt for the best CPU water cooling equipment that uses rubberized silicone, you will not have any issues getting good airflow, even when under heavy use. The length and quality of the hose connections should also be considered before making your purchase decision. Because having longer hoses makes installation much more effortless than short ones do.

Liquid Storage:

Liquid storage plays a significant role in determining which liquid cooler you should get. If there is not enough storage, your water pump will have to work harder than it needs to, reducing its lifespan over time. However, if there is too much storage, then the risk of leakage increases significantly.

Conclusion:

The 10 best CPU coolers are featured in the list above, but if you need more information about these products or how to pick a CPU liquid cooler for your computer system, check out our buying guide. We also have answers to some frequently asked questions like “An air cooler vs. water cooler?”. If you want even more details on any of them before making your decision, click through and read their individual reviews!

A CPU liquid cooler is an advanced version of the traditional fan and heat sink cooling system used in desktop computers for over a decade now. It uses a pump to circulate water through small tubes fitted with radiator fins which dissipate heat from the central processing unit (CPU) using coolant.

It works just like your car’s radiator, with water flowing through small tubes and air passing over the fins. The pump circulates water through a radiator, drawing heat from your PC components and passing it to the coolant in the loop. A fan on top of the radiator exhausts warm air back into your case.

Liquid coolers are more effective than air coolers at keeping your processor running at lower temperatures. This is because water has a higher heat transfer rate. This means that it can move the heat away from your CPU faster than the air cooler. Also, air coolers tend to disperse the heat in the case while liquid coolers expel it away. And if we talk about aesthetics, then liquid coolers are unparalleled in that domain too.

On the downside, liquid coolers can be more expensive to purchase upfront if you are on a tight budget. Few models of liquid cooler can also be challenging to install sometimes. But at the end of the day, it depends upon your preferences. We have given you a detailed difference between both coolers, now it depends on your choice. Happy cooling!
