Among the most suitable solutions for a high-end PC is the AIO CPU cooler. It is one of the most prominent cooling devices today for those users who want to get a high-performance PC.

Heat is the main enemy, especially for those who want to enjoy games with high requirements. When a PC does not have the right cooling solution, it is possible to notice some temperature problems. To find out if this component is working, we have developed the following information below.

What is an AIO CPU cooler?

All-in-one liquid coolers are one of the most efficient components when it comes to getting a high-performance CPU. This component consists of a radiator with tubing that is connected to a pump or block combo. It is a liquid cooling unit that operates in a stand-alone mode.

Initially, the path transfers the heat from the component to the block. The block then transfers the heat to a liquid. This liquid can be a special cooling liquid or distilled water. In turn, the liquid is pushed by the pump through the pipe to the radiator.

The fans dissipate the heat installed precisely in the radiator. This lowers the temperature of the radiator fins. In a large number of cases, the pump blocking unit is usually installed in the CPU. In turn, the fans and the radiator are usually installed in the case. This cooling unit is also often placed on graphics cards.

This cooling concept is novel because it results in a higher potential than conventionally designed air coolers. This means that a more powerful computer will incorporate this cooling unit when it has to cope with a heavy workload from different activities.

Even users interested in aggressive overclocking will be able to incorporate this cooling unit to obtain a high-end CPU. It is also a high-end unit that requires less space compared to air coolers. This requires all the appropriate accessories for the installation of the radiator.

When it comes to cases with limited airflow, conventional air coolers do not give a great result. In such situations, these AIO CPU coolers can provide a better lifetime result, which manages to contain as much heat as possible within the cooling circuit.

How Do You Know if the AIO CPU Cooler is Working or Not?

How Do You Know if AIO CPU Cooler is Working or Not?

There are a few ways to detect if this cooling device is genuinely working. One way is to raise the CPU temperature to above 80 degrees Celsius. When the CPU more a great fan or pump is not running, there is some failure.

Also, when the fans or pump of this device are not running, the CPU may automatically shut down. This is because the processor is trying to decrease the damage that could occur due to high temperatures. Sometimes a CPU that is constantly slowing down can be the result of a malfunctioning cooler.

There is much software such as HW monitor that allows you to check the CPU clock history. This will allow you to compare the maximum clock speed of the processor with the results that this history can show.

Another method to check the operation of the liquid cooler pump is to determine the RPM of this part. It is possible to obtain an RPM reading when the cable from this port is connected to a fan header on the motherboard directly. It is possible to use the same software mentioned above to check the RPM of the pump.

How to Test a CPU Cooler?

To check the operation of a CPU cooler, the following steps must be followed:

  • Download and install the software:

Some programs such as Speedfan allow you to collect information from the sensors in the cooler. This type of software provides certain critical information, such as the speed of the cooler’s fans or the temperature of different CPU components. Once this program is installed, it is necessary to start and wait for data retrieval.

  • Check information:

This program will provide preliminary information, such as data referring to the speed of the fans or the temperature of the different components. Data such as the revolutions per minute of the more fantastic fan should be compared with the specification manual.

  • Incorporate graphs:

This program, among others, allows incorporating some graphs to analyze the cooler’s performance over time. To do this, it is necessary to leave the computer running so that the software can analyze the operation of the fan for some time.

How Can I know if the Cooler is Strong Enough for the CPU?

There is an essential aspect that must be considered in the CPU to choose the suitable cooler. When it is a 125-watt CPU, the cooler should be at least 125 watts. This is the power of the processor that must be compared to the cooler.

When the cooler has less power than the CPU, the results will not be adequate, and all the temperature will not dissipate. When the cooler exceeds the CPU power, this means that the processor will be more fantastic. Even the noise level generated by the fan should be lower and quieter.


Different programs can be used to analyze and control the operation of the AIO CPU cooler. In any case, specific considerations must be taken into account for this component. First, it is necessary to check that it is a new component utterly free of any possible damage.

When it is a new cooler, the power in watts must be checked. This power must exceed, or at least equal, the wattage of the CPU. When this happens, it will be possible to use the CPU at its maximum performance without worrying about excessive temperature rise. Lowering the processor temperature means avoiding noticeable damage to sensitive components.
