Choosing an AIO CPU cooler: a practical guide for gamers and PC builders

An AIO CPU cooler can keep a powerful processor cool while freeing up space around the socket. However, an all-in-one liquid cooler won’t automatically suit every PC. The radiator needs to fit inside your case, the pump must be compatible with your socket, and the fans can become audible under heavy load.

These are the three most common pitfalls to watch out for:

  • Choosing based only on RGB lighting: ARGB or RGB makes no difference to cooling capacity. Check the radiator size, fan speed and PWM control too.
  • Buying a radiator without measuring your case: A 360mm liquid cooler needs space for three 120mm fans and the radiator. Not every case supports top or front mounting.
  • Assuming socket compatibility: Check that the included bracket suits your processor. Intel LGA 1700, Intel LGA 1851, AMD AM4 and AMD AM5 don’t always use the same mounting hardware.

Which specifications matter?

1. Radiator size: 240mm or 360mm

A 240mm liquid cooler typically uses two 120mm fans. This size fits more midi-tower cases and is often a practical choice for gaming PCs where space is limited.

A 360mm liquid cooler uses three 120mm fans. The larger radiator offers more surface area for heat dissipation, but you’ll need a suitable case. As well as the length, check the combined thickness of the radiator and fans. Memory modules, a tall motherboard heatsink or a long graphics card can affect how it fits.

2. Airflow, static pressure and noise levels

Both airflow and static pressure matter for radiator fans. Airflow is often measured in CFM or m³/h. Static pressure, measured in mmH2O for example, indicates how well a fan can push air through a dense radiator.

Only compare figures measured under similar conditions. A stated noise level, such as 33,2 or 34 dB at high speed, doesn’t mean the cooler will be that loud during everyday use. PWM control and a custom fan curve can help keep noise levels down. Also check whether the pump and fans connect separately.

3. Sockets and connections

Check the official compatibility list before buying. Depending on the model, the products in this selection support:

  • Intel LGA 1700 coolers for compatible Intel processors;
  • Intel LGA 1851 coolers for recent Intel platforms;
  • AMD AM4 coolers for older and still widely used AMD systems;
  • AMD AM5 coolers for recent Ryzen platforms.

Also check the connections. A 4-pin PWM connector enables automatic control via your motherboard. ARGB lighting often requires a 5V 3-pin connector. An LCD display may need additional software, so check in advance that your motherboard has enough connectors.

Installation and maintenance

An AIO cooler is usually a sealed system. Don’t dismantle or open the cooling unit yourself, as this could cause leaks and damage your hardware. Keep these points in mind when installing it:

  1. Use only the correct bracket for your socket.
  2. Position the radiator according to the manufacturer’s instructions.
  3. Connect the pump to a suitable AIO_PUMP or CPU_FAN header.
  4. Connect the PWM and ARGB cables correctly to the motherboard.
  5. Keep the radiator and fans free of dust.

According to the product information, the models listed come with a minimum two-year statutory warranty. Additional rights may apply under the relevant Dutch legislation.

Frequently asked questions about CPU liquid coolers

Is a 240mm liquid cooler enough for gaming?

A 240mm radiator can be a practical choice for many gaming systems. The cooling capacity you need depends on the processor, power consumption, configured limits and airflow inside the case. So check not only the radiator, but also its dimensions and fan position.

How long does an AIO liquid cooler last?

Lifespan varies by model and conditions of use. Dust, high temperatures and incorrect installation can affect performance. You shouldn’t refill or open a sealed AIO cooler. Check regularly for unusual noises, loose cables or visible leaks.

Does an ARGB liquid cooler use a lot of power?

The pump and fans typically use more power than the lighting alone. Exact consumption varies by model and fan speed. ARGB usually has only a limited impact on overall power use, but it does require a suitable 5V 3-pin connector or the included controller.
