Maintaining the proper temperature in a computer, and especially in the CPU, is one of the most important points to maintaining good PC performance and extending its useful life as much as possible.

Having an adequate cooling system is essential to keep the temperature of the computer at acceptable levels, especially at times of the year when it is hot and if you use your computer a lot for demanding activities such as graphic design or gaming. A good cooling system prevents damage to computer towers, ATI graphics, and PC computers.

Choosing the type of cooling is such an important decision as choosing a computer tower, the PC computer, the type of PC ventilation (Coolbox Twister,  Scythe Katana 4 Intel/AMD, etc), or the gaming motherboard when buying. a gaming computer.

Today we are going to compare liquid CPU coolers with air coolers, so you can choose the option that best suits your needs and the use you give your computer. Stay with us!

CPU Liquid Cooling vs Air Cooling

Although there are other means of cooling for computer equipment, only air or liquid cooling is used in domestic environments , which offer sufficient performance to keep our equipment within the appropriate temperature limits for proper operation.

Cooling is a fundamental factor if you are a gamer, and you have gaming products such as gaming towers , gaming computers, or ATI graphics cards , since these elements use a lot of RAM and cooling is needed.

Types of liquid cooling

Although in this article we are going to limit ourselves to liquid CPU coolers, it is important that you know that there are also other options, such as modular liquid coolers, which allow you to cool all parts of the computer and not just the processor.

These coolers have a higher performance than air coolers, keeping the general temperature lower as they dissipate heat more effectively, the only cons they have are the price that is higher, the assembly that is more complicated than cooling by air, and that requires refilling the liquid every 3-6 months to keep the system in optimal conditions.

In general, they are used for high-performance computers that produce high temperatures when used and are not recommended for all users due to their maintenance and complexity, instead, there are simpler alternatives such as air cooling and liquid cooling only for CPU, with which very good results can also be obtained.

We will then compare CPU cooling with air coolers, excluding the option of modular liquid cooling that we will leave for other articles.


In terms of performance, we are clear, liquid cooling comes out ahead, and they are able to maintain a lower temperature than air cooling.


This is because they have a closed liquid circuit that is responsible for transporting the coolest liquid to the processor, absorbing its heat, and then transporting it to fans that will cool it down to start the cycle again.

In an air-cooled system, a current is simply generated inside the box that allows it to stay relatively cool and within acceptable levels.

Essentially closed-loop CPU liquid cooling adds an extra step to cooling to put it simply, making it more effective.


Adding an additional cooling system to a computer always takes up space, the heatsinks that come standard with processors are as small as they are inefficient.

The air coolers that are placed on the CPU, in general, are quite large, so you will need a wide box to install them since in many models they simply will not fit.

Closed circuit CPU coolers require space in the case because you have to put a radiator with one or two fans on one of its sides and it can be installed in almost all cases, you just have to take into account that the placement is adequate with the cooling model that you are going to choose, since the part that connects to the CPU is very small, so it does not need as much space to install it.


Not all of them are noisy, but low and mid-range air coolers can get quite noisy when running at a high level, higher end air coolers are usually barely noisy even at high performance.

On the other hand, liquid cooling is very quiet, since it dissipates mainly through the liquid and does not depend entirely on the revolutions of your radiator fans.


Although liquid coolers require quite specific and regular maintenance, closed-loop liquid coolers do not require liquid refilling, they only require regular cleaning of their radiator fans that you can perform when you clean the rest of the dirt from the computer case.

Air coolers are also not too complicated to maintain, you just have to make sure to keep the fans clean so that they can take heat away from the components of the computer.

In both cases, you should think about cleaning all traces of dust or dirt from the equipment every 6 months, changing the thermal paste every 6 months – 1 year, and cleaning the cooling systems every time you clean the equipment.


This is the point where there are perhaps more differences since liquid cooling is more expensive than air cooling.

However, this is more significant in mid-range and low-end models, because in high-end models there is not as much difference in price.

In summary

Both liquid cooling and air cooling can keep a home computer in optimal temperature conditions if it is properly maintained, the difference is that liquid cooling will have a higher performance and its price will also be higher, which is why it is recommended for computers that are used very intensively.

For equipment that is used sporadically, it is not such a necessary investment, with an air cooling system it will be enough.

Our recommendation, in any case, is that you always replace the heatsink that comes with the standard processors, since its power is enough so that it does not burn out but little else, as soon as you ask the processor for a bit of performance, the temperature will rise very Quick.
