AIO Liquid Cooling: Pros And Cons You Need To Know Before Buying

More and more users are using AIO (All In One) liquid cooling, leaving aside conventional air coolers. This new cooling system has a major disadvantage compared to classic heatsinks: the coolant must be replaced from time to time. But it also has a wide variety of advantages that make it the most advanced cooling system at the moment.

In today’s article, we are going to explain why you should (or should not) mount an AIO liquid cooling system on your PC.

Differences between AIO liquid cooling and conventional air coolers

An AIO liquid cooling system consists of a pump that moves a refrigerant liquid within a sealed closed circuit. With the passage of time and due to the effect of evaporation, this liquid decreases, and its performance decreases.

On the contrary, conventional air sinks are usually aluminum and copper sheets. It is the only component with moving parts. But before continuing, learn which is the best cooling for your computer: liquid or air cooling.

This cooling method can last you years, but you will inevitably have to replace it. If your device is properly maintained and cleaned, it will be able to function for many years without problems. The duration of the liquid is also affected by the weather.

Possibly, you wonder if these refrigerators are effective or not. The truth is that the best liquid cooling kits are much more effective than traditional coolers. If you’re building your PC or just want to customize it, these coolers are easy to install and also leave the hardware visible (although this can have its drawbacks).

Now, we are going to talk about the signs that your device is giving you to change your system to AIO liquid cooling :

  • Your processor heats up very quickly, the temperature is higher than when you started using AIO cooling. You can clean some components that influence temperature, how clean the radiator and fans, or change the thermal paste. If when making these changes, you continue with a high temperature, it is possible that the pump has been damaged and it does not have enough force to move the liquid through the circuit or that it is insufficient.
  • Noise: Generally, this noise does not come from the fans. If so, you just have to clean it (which never hurts to clean it). This noise usually comes from the pump, a movement similar to that of two pieces rubbing against each other, this means that it does not have enough force to carry out the circuit.

The bad of AIO liquid cooling

Most AIO liquid cooling systems have a fairly long lifespan and usually have the same life as any other component in your computer.

The biggest but that we can put to this component is that it is a hermetic circuit, completely closed. This does not allow us to replace or replenish the liquid or change the sleeve that pumps, but it is necessary to replace the entire circuit completely.

To better talk about the wear of the AIO dissipation system, we are going to talk about the different parts and the possible failures that may cause

  • Fans: All liquid cooling systems have at least one radiator incorporated. Over time, dust and dirt settle on the edges then the fan gets stuck, starts to make noise, and loses its efficiency. All this can be avoided with a good maintenance cleaning every 6 months.
  • Radiator: It has a fundamental task when it comes to avoiding high temperatures in our computer. It is in direct contact with the fans, so they also accumulate dirt. Just like fans, with a good cleaning they don’t have to cause a lot of trouble.
  • Pump: It is in charge of moving the refrigerant liquid throughout the circuit. If leaks appear, it loses effectiveness, works slower, and makes more noise. The downside of this part is that there is no maintenance, when it starts to fail, you have to change it.
  • Coolant liquid: It is responsible for collecting the heat and transferring it to the radiator to cool it. These systems are not completely hermetic and may suffer small losses of liquid. Over time, air bubbles may form. If your kit allows you to recharge it, experts advise recharging it every two years.
  • Water block: Some kits incorporate these water blocks that protect against rust and leaks. It is recommended to perform a good cleaning every 6 months and change the thermal paste at least every twelve months.

For many people the answer is obvious, however, for beginners, it can be confusing. Like almost all components, it has many options and several answers. That is why in this article we are going to try to solve all your doubts about AIO liquid cooling. That is why we have compiled all the most frequently asked questions in forums to try to answer them.

Do you really need an AIO liquid cooling system?

In the vast majority of cases, the answer is yes. Because if you don’t use it, your CPU could break down. But let’s focus on more specific questions.

When I change my CPU: is it necessary to change the cooling system?

Well, the answer to this question depends on how good your current cooler is and the most important issue: component compatibility.

Let’s give an example: If you are using a Noctua NH-D15 or any cooler of similar power and the technological leap of your new CPU is not very great, you can possibly continue using it until you have to replace it due to wear.

How to know if the cooler and CPU are compatible?

  • The first thing is to check that you can mount it in the socket of your CPU. In most cases, you can find compatible adapters for your CPU.
  • Check that your cooler is powerful enough to cool your new CPU. To be safe, the TPD (Thermal Desing Power) should match that of your cooler, but we recommend that you leave a margin between them.

In this case, if they are compatible both to mount it in the slot and to comply with the TPD, it would not be necessary to change it.

My CPU won’t overclock: do I need a cooler?

The answer is no, as it would be a waste of money. In this case, we recommend using a good fan rather than a cheap AIO liquid cooler. Since it does not have so many moving parts and the space it requires is less.

The only reason that would lead us to choose the AIO System for PCs that we do not get the most out of overclocking would be purely a personal decision and not out of necessity.

If my CPU overclocks, do I need a cooler?

In this case, the answer is yes. In this way, you will save your CPU from making thermal shutdowns to cool down and prevent it from burning out carrying out tasks that reach high temperatures.

In this case, we must say yes. It is very important to have a refrigerator for this type of task.

Do CPUs have their own cooling system?

Some of them do, but most CPUs that fall into the maximum power spectrum do not have a built-in cooler. The reason is that the CPU TPD emits so much heat that it would be a waste of resources to include a medium cooler when you need a strong cooler to keep the CPU running at acceptable temperatures.

Is the cooler that comes standard enough?

Well, it depends on the use you are going to give it. If you use it to carry out simple tasks, the built-in cooler is more than enough.

However, if you carry out more complex tasks such as complex calculations and perform video compression or rendering tasks, you may need to replace the cooler.

In either case, the standard cooler is tailored to cool the CPU for simple, everyday tasks. However, CPU performance is tied to temperature. Therefore, by replacing the cooler, you will improve performance.

Does a CPU work without its cooler?

This question is very ambiguous and difficult to answer since nowadays you cannot turn on your computer without the motherboard making sure to have a heatsink with fans installed.

The motherboard checks if there is a fan running and therefore assumes that a cooler is installed next to it.

If you carry out simple tasks, your CPU may not suffer and it can work without problem. But if you carry out complex tasks, it may shut down to cool down before damaging your CPU. So you won’t break your CPU if you don’t use a cooler, but you will reduce its useful life.

You can do it, but it is something that we strongly discourage since it can cause serious damage to your CPU

Does a CPU work without its fan?

It depends on the type of cooler and the type of CPU. If you have for example a CPU with a low TPD and the radiator is acceptable, you may not need a fan to dissipate the heat. However, you must make sure that you have a case with good ventilation to facilitate the escape of air.

In summary

As you have seen, there are many factors that influence when deciding to change our AIO liquid cooling system. Before spending a lot of money on this component, consider all the options, their benefits, and drawbacks, and make the decision that is most sensible for your pocket and your needs.

And you, what type of refrigeration do you use? We read you in the comments.
